Regioselective 2-Imino-1,3-thiazolidine vs. 2-Imino-1,3-oxazolidine Formation from the Vicinal sec-Amino Alcohol of Desosamine

In order to optimize Mukaiyama reagent-induced cyclization of vicinal sec-amino alcohols of desosamine origin towards exclusive formation of N-substituted-2-imino-1,3-thiazolidines via a thiocarbamoyl intermediate, the influence of reaction conditions was studied. A novel, mild, one-pot, two-step method was developed, and the formation of N-substituted-2-imino-1,3-oxazolidines as side products was minimized. The inversion of configuration at C-2 was unambiguously established using NMR-based conformational analysis. A reaction mechanism was proposed. A test series of novel desosamine-modified 14- and 15-membered macrolides, bearing N-alkyl-2-imino-1,3-thiazolidines fused to the desosamine sugar were prepared.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 6704-31-0 is helpful to your research. SDS of cas: 6704-31-0.

Glucosinolate turnover in Brassicales species to an oxazolidin-2-one, formed via the 2-thione and without formation of thioamide

Glucosinolates are found in plants of the order Brassicales and hydrolyzed to different breakdown products, particularly after tissue damage. In Barbarea vulgaris R.Br. (Brassicaceae), the dominant glucosinolate in the investigated G-type is glucobarbarin, (S)-2-hydroxy-2-phenylethylglucosinolate. Formation of the nitrile from glucobarbarin was observed in vitro, while a previously suggested thioamide (synonym thionamide) was not confirmed. Resedine (5-phenyl-1,3-oxazolidin-2-one) was detected after glucobarbarin hydrolysis in crushed B. vulgaris leaves and siliques, but not in intact parts. The abundance increased for several hours after completion of hydrolysis. The corresponding 1,3-oxazolidine-2-thione (OAT), with the common name barbarin, was also formed, and appeared to be the precursor of resedine. Addition of each of two non-endogenous OATs, (S)-5-ethyl-5-methylOAT and (R)-5-vinylOAT (R-goitrin), to a leaf homogenate resulted in formation of the corresponding 1,3-oxazolidin-2-ones (OAOs), confirming the metabolic connection of OAT to OAO. Formation of OAOs was inhibited by prior brief heating of the homogenate, suggesting enzyme involvement. We suggest the conversion of OATs to OAOs to be catalyzed by an enzyme (oxazolidinethionase) responsible for turnover of OAT formed in intact plants. Resedine had been reported as an alkaloid from another species – Reseda luteola L. (Resedaceae) – naturally containing the glucosinolate glucobarbarin. However, resedine was not detected in intact R. luteola plants, but formed after tissue damage. The formation of resedine in two families suggests a broad distribution of putative OATases in the Brassicales; potentially involved in glucosinolate turnover that needs myrosinase activity as the committed step. In agreement with the proposed function of OATase, several candidate genes for myrosinases in glucosinolate turnover in intact plants were discovered in the B. vulgaris genome. We also suggest that biotechnological conversion of OATs to OAOs might improve the nutritional value of Brassicales protein. HPLC-MS/MS methods for detection of these glucobarbarin products are described. (C) 2018 Elsevier Ltd. All rights reserved.

New Regio- and Stereoselective Cascades via Unstabilized Azomethine Ylide Cycloadditions for the Synthesis of Highly Substituted Tropane and Indolizidine Frameworks

Multisubstituted tropanes and indolizidines have been prepared with high regio- and stereoselectivity by the [3+2] cycloaddition of unstabilized azomethine ylides generated from readily prepared trimethylsilyl-substituted 1,2-dihydropyridines via protonation or alkylation followed by desilylation. Starting from 1,2-dihydropyridines bearing a ring trimethylsilyl substituent at the 6-position, an intermolecular alkylation/desilylation provides endocyclic unstabilized ylides that successfully undergo cycloaddition with a range of symmetrical and unsymmetrical alkyne and alkene dipolarophiles to afford densely substituted tropanes incorporating quaternary carbons in good yields and with high regio- and stereoselectivity. Additionally, an intramolecular alkylation/desilylation/cycloaddition sequence provides convenient and rapid entry to bridged tricyclic tropane skeletons, allowing for five contiguous carbon stereocenters to be set in a single experimental operation and under mild conditions. Starting from 1,2-dihydropyridines with trimethylsilylmethyl groups on nitrogen, protonation followed by desilylation generates exocyclic unstabilized ylides that undergo cycloaddition with unsymmetrical alkynes to give indolizidines with good regio- and stereoselectivity. N-Trimethylsilylmethyl-1,2-dihydropyridines can also be alkylated and subsequently desilylated to give endocyclic unstabilized ylides that undergo intermolecular cycloadditions with carbonyl compounds to give bicyclic oxazolidine products in good overall yields. Moreover, an intramolecular alkylation/desilylation/cycloaddition sequence with the N-trimethylsilylmethyl-1,2-dihydropyridines affords tricyclic indolizidines that incorporate quaternary carbons and up to five stereocenters with good to excellent regio- and diastereoselectivity.

Oxa- and Thiazolidine-Containing Polymers Derived via the Asinger Four-Component Reaction: the Ring Matters

Novel structural motifs in macromolecular chemistry are introduced by the use of the Asinger multicomponent reaction. The combination of ammonia, acetone, -chloroisobutyraldehyde, and either water or sodium hydrosulfide, leads to an oxazoline or thiazoline scaffold, respectively, which is subsequently modified with 10-undecenol and 10-undecenoyl chloride to obtain heterocycle-functionalized ,-dienes. These substrates are used as monomers in an acylic diene metathesis (ADMET) or thiol-ene step-growth polymerization. The thus-obtained polymers are studied in post-polymerization modifications, like hydrogenation and oxidation. Here, the thiazolidine- and oxazolidine-containing polymers show dramatically different chemical stability due to the heterocyclic moieties.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 6704-31-0. Recommanded Product: Oxetan-3-one.

CuI/CuBr2-catalyzed decarboxylative/A(3) reaction of propiolic acids for the facile synthesis of 1,4-diheterocycle-2-butynes

A novel and efficient microwave-assisted protocol to 1,4-diheterocycle-2-butynes was successfully developed. The method is based on one-pot copper-catalyzed A(3) reaction/decarboxylative coupling of a propiolic acid, a formaldehyde, and a 1,2- or 1,3-amino alcohol. This multicomponent coupling reaction provides a straight forward access to introduction oxazolidine or 1,3-oxazinane at the 1,4-position of a but-2-yne from readily available starting materials. 1,4-Diheterocycle-2-butynes with diverse substitution patterns are obtained in moderate to good yields.

A Novel Oxazolidine Tanning Agent and its Use in Vegetable Combination Tanning

Combination tanning using vegetable tannins and oxazolidine E has been proved to be a preferred alternative to chrome tanning. But this kind of tannage has not been widely applied partly owing to the high price of oxazolidine E. In this study, a new oxazolidine tanning agent, oxazolidine SCU, was synthesized by using cheap and readily obtained raw materials, and its tanning properties both alone and in combination with vegetable tannins, were investigated. Oxazolidine SCU possesses high reactivity with skin collagen. Tanned by 5% oxazolidine SCU under room temperature at pH8.0, the shrinkage temperature of goatskin leather was around 83 degrees C. In vegetable combination tanning, oxazolidine SCU exhibited a good synergistic tanning effect with condensed tannins. Among condensed tannins, mimosa is the preferred one in consideration of achieving high shrinkage temperature of leather. Tanning the depickled pelt with 10-15% vegetable tannin at first, and then retanning with 4-6% oxazolidine SCU for 4 hours at 60 degrees C in the pH range 5.5-6.0, the shrinkage temperature of leather was 114-120 degrees C.

Zinc(II) complexes with uncommon aminal and hemiaminal ether derivatives: synthesis, structure, phosphatase activity and theoretical rationalization of ligand and complex formation

Condensation of N-(2-hydroxyethyl)ethylenediamine and pyridine-2-carbaldehyde in the presence of ZnX2 salts (X = ClO4-, Cl-, Br-, I-) generates four complexes, namely, [ZnL1Cl](ClO4) (1), [ZnL1Cl][ZnCl3(H2O)]center dot 2H(2)O (2), [ZnL1Br][ZnBr3(H2O)]center dot 2H(2)O (3), and [Zn(L2)(3)]I-2 (4), where L1 and L2 are aminal and hemiaminal ether derivatives, i.e., (E)-N-((pyridine-2-ypmethylene)-2-((2-pyridine-2-yl)oxazolidin-3-yl)pethanamine and 2-(2-pyridin-2-yl-imidazolidin-1-yl)-ethanol, respectively. No complex with the expected Schiff-base ligand (E)-2-(2-(pyridin-2-ylmethyleneamino)ethylamino)ethanol (L) or with 2-(2-pyridyl-3-(2-hydroxyethyl))oxazolidine (L3) was obtained. The structures of complexes 1, 3, and 4 have been elucidated by single crystal X-ray diffraction. All the complexes have been characterized by detailed NMR (H-1, C-13 and DEPT-135) and ESI-MS analyses, indicating retention of solid state structures in the solution phase. Complex 1 deserves special mention as during its formation, the ClO4- ion undergoes reduction to Cl- and thus, it forms a mixed anionic ligand complex. Thorough DFT calculations have been performed at the BP86-D3/def2-TZVP level of theory to rationalize the ligand and complex formation. The calculations suggest that the aminal form (L1) is the most favored species followed by the Schiff-base, whereas the hemiaminal ether form (L3) is the least preferred one. The role of halides during the formation of the monoanionic [ZnX3(H2O)](-) species is crucial, and the achieved complex is highly favored when X = Cl and disfavored for X = I; this trend has been rationalized by the DFT calculations. The phosphatase activities of the complexes have been investigated, and their efficiencies follow the order 2 > 1 > 3 > 4.
