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. Category: oxazolidines.

Synthesis and characterization of different types of epoxide-based Mannich polyols from low-cost cashew nut shell liquid

Cashew nut shell liquid (CNSL) is a natural aromatic organic oil consisting of phenolic compounds with interesting structures. Extraction of CNSL was performed in a Soxhlet apparatus. The major (90 %) component of CNSL is anacardic acid, which is easily decarboxylated to cardanol (10 %) by use of conventional methods. In this paper we describe a three-step synthesis of Mannich polyols for rigid foams. The first step is synthesis of N-(2-hydroxyethyl)-1,3-oxazolidine (the Mannich precursor) by condensation of paraformaldehyde and diethanolamine. The second step involves synthesis of the Mannich base phenolic ring of cardanol by reaction with N-(2-hydroxyethyl)-1,3-oxazolidine. The third step is alkoxylation. The synthesized polyols were characterized by FTIR and H-1 NMR spectroscopy and thin-layer chromatography.

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 16251-45-9. Quality Control of (4S,5R)-4-Methyl-5-phenyloxazolidin-2-one.

Spirocyclic Nitroxides as Versatile Tools in Modern Natural Sciences: From Synthesis to Applications. Part I. Old and New Synthetic Approaches to Spirocyclic Nitroxyl Radicals

Spirocyclic nitroxyl radicals (SNRs) are stable paramagnetics bearing spiro-junction at alpha-, beta-, or gamma-carbon atom of the nitroxide fragment, which is part of the heterocyclic system. Despite the fact that the first representatives of SNRs were obtained about 50 years ago, the methodology of their synthesis and their usage in chemistry and biochemical applications have begun to develop rapidly only in the last two decades. Due to the presence of spiro-function in the SNRs molecules, the latter have increased stability to various reducing agents (including biogenic ones), while the structures of the biradicals (SNBRs) comprises a rigid spiro-fused core that fixes mutual position and orientation of nitroxide moieties that favors their use in dynamic nuclear polarization (DNP) experiments. This first review on SNRs will give a glance at various strategies for the synthesis of spiro-substituted, mono-, and bis-nitroxides on the base of six-membered (piperidine, 1,2,3,4-tetrahydroquinoline, 9,9 ‘(10H,10H ‘)-spirobiacridine, piperazine, and morpholine) or five-membered (2,5-dihydro-1H-pyrrole, pyrrolidine, 2,5-dihydro-1H-imidazole, 4,5-dihydro-1H-imidazole, imidazolidine, and oxazolidine) heterocyclic cores.

Fluorescent triazolyl spirooxazolidines: Synthesis and NMR stereochemical studies

Carbon-heteoratom chemistry is a method of choice for rapid construction of complex molecules. In the recent decade, its various applications flourished thanks to the click chemistry approach. Herein, we use a combination of C-X bond formation reactions to complete the synthesis of 1,2,3-triazolyl spirooxazolidines, bearing the fluorenylmethoxycarbonyl (fmoc) substituent. Thanks to the application of 2D-NMR spectroscopic methods and a multilevel computational approach, including a medicinal chemistry – inspired conformational search, PM7 semiempirical and DFT-based geometry optimization finalized with DFT-GIAO NMR shielding constant calculation, we were able to investigate the conformational space and assign cis/trans configuration in complex NMR spectra. For the obtained fmoc derivatives we recorded UV-VIS absorption and emission spectra. The obtained compounds contain pharmacophoric groups characteristic for endocannabinoid system modulators- CB1 receptor ligands or FAAH inhibitors. (C) 2019 Elsevier B.V. All rights reserved.

Stereoselective synthesis and application of tridentate aminodiols derived from (+)-pulegone

A library of tridentate aminodiols, derived from naturally occurring (R)-(+)-pulegone, was synthesized and applied as chiral catalysts in the addition of diethylzinc to benzaldehyde. The reduction of pulegone furnished pulegol, which was transformed into allylic trichloroacetamide via Overman rearrangement of the corresponding trichloroacetimidate. The protected enamine was subjected to dihydroxylation with OsO4/NMO system resulting in a 1:1 mixture of (1R,2R,4R)- and (1S,2S,4R)-aminodiol diastereomers. After the removal of the trichloroacetyl protecting groups, the obtained primary aminodiols were transformed into secondary ones. The regioselectivity of the ring closure of the N-benzyl substituted aminodiols with formaldehyde was investigated resulting in both the 1,3-oxazine and oxazolidine rings. The tautomerism of the spiro and fused ring systems was observed and its mechanism was studied by detailed DFT analysis by employing an IEFPCM solvent model to provide a more realistic representation of the experimental conditions. The obtained potential catalysts were applied to the reaction of benzaldehyde and diethylzinc with moderate to good enantioselectivity (up to 90% ee). (C) 2016 Elsevier Ltd. All rights reserved.
