General and stereoselective aminoxylation of biradical titanium(IV) enolates with TEMPO: a detailed study on the effect of the chiral auxiliary

A comprehensive analysis of the influence of the chiral auxiliary on the alpha-aminoxylation of titanium(IV) enolates with TEMPO indicated that (S) 4-tert-butyl-1-oxazolidine-2-thione is the most appropriate scaffold to provide a single diastereomer in high yields for a variety of substrates, which converts such a radical reaction into a highly chemo-and stereoselective oxidation.

Application of 84793-24-8, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 84793-24-8 is helpful to your research.

TANDEM REACTIONS INITIATED BY THE CONJUGATE ADDITION OF CHALCOGEN COMPOUNDS – UTILIZATION AND SYNTHESIS OF HETEROCYCLES

Alkynyl- and alkenylselenonium salts reacted with nucleophiles at the alpha- or beta-carbon depending upon the nucleophiles. The alpha-attack caused the addition-elimination reaction; i.e., the apparent substitution reaction and the beta-attack (the conjugate addition) generated an ylide, which brought about the tandem reaction to form a variety of heterocyclic compounds. Some new reactions proceeded via the selenuranes formed by the attack of a nucleophile on the positively charged selenium atom. An interesting tandem Michael-aldol reaction of enones (ynones) bearing a chalcogenide or a thioamide was developed. The reactions of the 1-[2-(methylchalcogeno)phenyl]propenones gave alpha-(alpha-hydroxyalkyl)enones (Morita-Baylis-Hillman adducts) after a work-up with Et3N. The reactions of the 3-cinnamoy1-1,3-oxazolidine-2-thiones with aldehydes gave tricyclic compounds with a bridgehead bound to four heteroatoms. The asymmetric reactions simultaneously induced four stereocenters, three of which are contiguous. Removal of the chiral auxiliary provided 1,3-diols bearing three consecutive stereocenters.

Diastereoselective alkylation reactions employing a new camphor-based 2-phenylimino-2-oxazolidine chiral auxiliary

A new camphor-based 2-phenylimino-2-oxazolidine chiral auxiliary was prepared and it was shown to be a particularly effective chiral auxiliary for asymmetric alkylations affording high yields and diastereoselectivities. The alkylation products were readily cleaved by simple alkaline hydrolysis to give alpha-alkylated carboxylic acids in good yield and in almost enatiomerically pure form. (C) 2014 Jun-Qi Nie.

Colorimetric detection of normetanephrine, a pheochromocytoma biomarker, using bifunctionalised gold nanoparticles

A simple and effective colorimetric method for the detection of normetanephrine (NMN), an O-methylated metabolite of norepinephrine, using functionalised gold nanoparticles is described. This metabolite is an important biomarker in the diagnosis of adrenal tumours such as pheocromocytoma or paraganglioma. The colorimetric probe consists of spherical gold nanoparticles (AuNPs) functionalised with two different ligands, which specifically recognize different functional groups in normetanephrine. Thus, a benzaldehyde-terminated ligand was used for the recognition of the amino alcohol moiety in NMN, by forming the corresponding oxazolidine. On the other hand, N-acetyl-cysteine was chosen for the recognition of the phenolic hydroxyl group through the formation of hydrogen bonds. The selective double molecular recognition between the probe and the hydroxyl and the amino-alcohol moieties of normetanephrine led to interparticle-crosslinking aggregation resulting in a change in the color of the solution, from red to blue, which could be observed by naked eye. The probe was highly selective towards normetanephrine and no color changes were observed in the presence of other neurotransmitter metabolites such as homovanillic acid (HVA) (dopamine metabolite), 5-hydroxyindoleacetic acid (5-HIAA) (serotonin metabolite), or other biomolecules present in urine such as glucose (Glc), uric acid (U.A), and urea. Finally, the probe was evaluated in synthetic urine with constituents that mimic human urine, where a limit of detection of 0.5 mu M was achieved. (C) 2019 Elsevier B.V. All rights reserved.

Ni-Catalyzed Deacylative Oxosulfonamidation of Vinyl Acetate

A simple and efficient method for the synthesis of benzoxazolidines from the reaction of sulfonamidoalcohol and vinyl acetate was reported. The Ni-catalyzed deacylation of vinyl acetate results in O-alkenylated intermediate, which subsequently undergoes intramolecular annulation to afford C2-alkylated benzoxazolidines. Scope of this method was also extended for the synthesis of other heterocycles of this class such as oxazolidine, benzoxazinolidine and benzimidazolidine. Halofunctionalization was also performed in-situ in a sequential fashion in the presence of a halogen source. Most importantly, this reaction operates under ligand-free conditions by using a bench-top catalyst and does not require any inert atmosphere or dry solvent or any expensive terminal oxidant.

Properties and Applications of Indolinooxazolidines as Photo-, Electro-, and Acidochromic Units

The aim of this chapter was to introduce the readers to indolinooxazolidines (IndOxa), a new family of molecular switches. First, in a short historical account their evolution is followed from their first appearance in the 1970s until today. The second section concentrates on the general structural features of the indolinooxazolidine motif, which are closely related to those of the spiropyrans. In the core of their chemistry lies the oxazolidine ring opening that is discussed in the following. Owing to the facility of the very same ring opening, they show chromophoric properties and can be addressed using different stimuli, such as light irradiation, change in electrical potential and pH. For this reason, the last three sections are devoted to provide a general understanding on their photo-, electro-, and acidochromic properties.

Protection of abasic sites during DNA replication by a stable thiazolidine protein-DNA cross-link

A basic (AP) sites are one of the most common DNA lesions that block replicative polymerases. 5-hydroxymethylcytosine binding, embryonic stem cell-specific protein (HMCES) recognizes and processes these lesions in the context of single-stranded DNA (ssDNA). A HMCES DNA-protein cross-link (DPC) intermediate is thought to shield the AP site from endonucleases and error-prone polymerases. The highly evolutionarily conserved SOS-response associated peptidase (SRAP) domain of HMCES and its Escherichia coli ortholog YedK mediate lesion recognition. Here we uncover the basis of AP site protection by SRAP domains from a crystal structure of the YedK DPC. YedK forms a stable thiazolidine linkage between a ring-opened AP site and the alpha-amino and sulfhydryl substituents of its amino-terminal cysteine residue. The thiazolidine linkage explains the remarkable stability of the HMCES DPC, its resistance to strand cleavage and the proteolysis requirement for resolution. Furthermore, its structure reveals that HMCES has specificity for AP sites in ssDNA at junctions found when replicative polymerases encounter the AP lesion.

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 34052-90-9. Safety of 1,3-Bis(4,5-dihydrooxazol-2-yl)benzene.

Alkaloids from Tabernaemontana divaricata combined with fluconazole to overcome fluconazole resistance in Candida albicans

Nineteen indole alkaloids including eleven new ones, taberdines A-K (1-11), were isolated from Tabernaemontana divaricata. Their structures were assigned by MS, NMR, single crystal X-ray diffractions, and ECD analyses. Alkaloid 1 is an aspidosperma-type monoterpenoid indole alkaloid and possesses a rearranged pyrrolidine moiety due to C-3 degradation, and 4 has a rare 1,3-oxazolidine moiety within iboga-type alkaloids. Alkaloids 2, 4, 6, and 11-19 combined with 5 mu g/mL fluconazole exhibited significant activity to reverse fluconazole resistance in Candida albicans strains while no one used alone showed any activities against the resistant strain.
