Abstract:
Oxazolidine is one of the crucial structural moieties of biologically active compounds. A salen–scandium triflate complex-catalyzed asymmetric (3 + 2) annulation of dialkyl 1-sulfonylaziridine-2,2-dicarboxylates and aldehydes generated optically active functionalized oxazolidine derivatives in moderate to good yields and good to excellent enantioselectivities and high diastereoselectivities. A reasonable reaction mechanism was proposed and rationalized the experimental results.

2,2′-Anhydro-1-(3′,5′-di-O-acetyl-β-D-arabinofuranosyl)uracil, C13H14N2O7, was obtained by refluxing 2′,3′-O-(methoxymethylene)uridine in acetic anhydride. The structure exhibits a nearly perfect C4′-endo(4E) conformation. The best four-atom plane of the five-membered furanose ring is O—C—C—C, involving the C atoms of the fused five-membered oxazolidine ring, and the torsion angle is only −0.4 (2)°. The oxazolidine ring is essentially coplanar with the six-membered uracil ring [r.m.s. deviation = 0.012 (5) Å and dihedral angle = −3.2 (3)°]. The conformation at the exocyclic C—C bond isgauche–t

The interaction of diethanolamine with formaldehyde at a ratio of initial reagents of 2?:?3, respectively, obtained a preparation that is an equimolar mixture of 3-(?-hydroxyethyl)-1,3-oxazolidine and its methylol derivative – 3-(?-hydroxyoxymethyl-ethyl)-1,3-oxazolidine. The paper presents the results of a study of the antimicrobial activity of the preparation against microorganisms – S. aureus, E. coli, as the most resistant species of bacteria that cause nosocomial infection. The tests were carried out by three methods: the test object method, as well as suspension and adsorption methods. T

Here, we describe the design, synthesis, and biological evaluation of oxazolidine derivatives. Oxazolidine ring is a reduced form of oxazole system; many of its derivatives possess interesting biological activities, such as anti-convulsant, anti-microbial, analgesic, anti-inflammatory and anti-tumor. In our study, the biological activity of synthesized novel 3-benzyl-2-(4'-substituted phenyl)-4(5H)-(4''-nitrophenyl amino)-1, 3-oxazolidines 6a-e were characterized by antimicrobial screening against several gram-positive, gram negative bacteria and fungus.

Dans ce but, nous avons développé une méthodologie de synthèse d'OZT spiraniques sur charpentes saccharidiques ainsi qu'une méthode de N-vinylation des OZT, en poursuivant les connaissances acquises au sein du laboratoire. La chiralité inhérente aux sucres, couplée à la réactivité toute particulière des OZT obtenues, nous a permis d'explorer la réactivité d'a

Abstract:
Glucosinolates (GLs) are a large group of secondary metabolites which are found in cruciferous plants such as broccoli, cabbage, and kale and contain nutritional and physiological active properties. Several factors affect composition levels of glucosinolates such as storage conditions, methods of consuming vegetables as well as agricultural and environmental factors. When cruciferous vegetables are consumed raw, the myrosinase enzyme found in these plants hydrolyzes the GLs in the proximal gastrointestinal tract to produce a variety of metabolites such as isothiocyanates, nitriles, oxazolidine

Abstract The study concerns a non-conventional field in the Middle East, where gas contains 4 mol% of H2S and 3 mol% of CO2. Gas is exported and production water is reinjected in the aquifer. The first target is to have H2S level in the injected water around 400 ppm and the second target is to have H2S level in the injected water lower than 60 ppm. Quantity of water to be treated will be around 10 000 bbl/d for the first weeks and decreasing up-to few 100s bbl/d after some months. The objective of this paper is (i) the evaluation of the scaling risk; (ii) identification of suitable H2S scaveng
