Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 84793-24-8, Name is Ethyl (S)-2-[(S)-4-Methyl-2,5-dioxo-3-oxazolidinyl]-4-phenylbutanoate, molecular formula is C16H19NO5, belongs to oxazolidines compound, is a common compound. In a patnet, author is Tsuno, Takashi, once mentioned the new application about 84793-24-8, Application In Synthesis of Ethyl (S)-2-[(S)-4-Methyl-2,5-dioxo-3-oxazolidinyl]-4-phenylbutanoate.

Synthesis and structural characterization of bis[(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine]copper(II) dichloride and bis[(4S,5R)-4-methoxycar-bonyl-5-methyl-2-oxazoline]-[(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine]ruthenium(III) trichloride

In the reaction of N,N’-methylenebis[(4S,5R)-4-methoxycarbonyl-5-methyloxazolidine] (1) with CuCl2 or RuCl3 in alcoholic solvents novel complexes, bis[(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine]copper(II) dichloride (2) and bis[(4S, 5R)-4-methoxycarbonyl-5-methyl-2-oxazoline]-(4S,5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidineruthenium(III) trichloride (3), respectively, were isolated and fully characterized by X-ray crystallography. In these reactions, which occurred under mild conditions, ligand 1 was cleaved at the bridging aminal position and degraded to (4S, 5R)-4-methoxycarbonyl-5-methyl-1,3-oxazolidine 5. The trigonal bipyramidal Cu complex 3 contains two such oxazolidine ligands coordinated in different ways. One is bonded in a monodentate fashion via the nitrogen atom of the five-membered ring, the other binds as a bidentate ligand, additionally using the carbonyl oxygen of the ester group. In the octahedral Ru complex 4 there are one oxazolidine ligand 5 and two oxazoline ligands 6. Thus, in the synthesis of 4 the carbon atom between oxygen and nitrogen in the oxazolidine ring was partly oxidized from the half-aminal status to the carboxamide status. (C) 2012 Elsevier B. V.

Stereospecific Electrophilic Fluorocyclization of alpha,beta-Unsaturated Amides with Selectfluor

An efficient fluorocyclization of alpha,beta-unsaturated amides through a formal halocyclization process is developed. The reaction proceeds under transition-metal-free conditions and leads to the formation of fluorinated oxazolidine-2,4-diones with excellent regio- and diastereoselectivity. The evaluation of the reaction mechanism based on preliminary experiments and density functional theory calculations suggests that a synergetic syn-oxo-fluorination occurs and is followed by an anti-oxo substitution reaction. The reaction opens a new window in the field of stereospecific fluorofunctionalization.

Versatile synthesis of 2 ‘-amino-2 ‘-deoxyuridine derivatives with a 2 ‘-amino group carrying linkers possessing a reactive terminal functionality

2,2′-Anhydrouridine has been successfully converted into the appropriate 2′-amino-2′-deoxyuridine derivatives in a reaction with isothiocyanates obtained from amino acids or alpha,omega-diaminoalkanes. The initially formed oxazolidine-2-thione ring is cleaved under basic conditions into the corresponding 2′-amino(substituted)-2′-deoxyuridine derivatives. The implemented additional terminal functionality in the substituent attached to the 2’-amino group allows further modifications with e.g., fluorophore moiety. (C) 2016 Elsevier Ltd.

Atropo- and Diastereoselective Construction of Tetracyclic Biphenylazepinium Salts Derived from Aminoalcohols: Use as Catalysts in Enantioselective Asymmetric Epoxidation

A range of new biphenylazepinium salt organocatalysts effective for asymmetric epcondation has been developed incorporating an additional substituted oxazolidine ring, and providing improved enantiocontrol in alkene epoxidation over the parent structure. Starting from enantiomerically pure aminoalcohols, tetracydic iminium salts were obtained as single diastereoisomers through an atroposelective oxazolidine formation.

Total Synthesis and Bioactivity of ent-homospisulosine and N,O-diacetylhomoclavaminol A

Background: Over the past decade, simple 1-deoxysphingoid bases with a saturated hydrocarbon sidechain such as spisulosine, xestoaminol C, 3-epi-xestoaminol C, clavaminol A have attracted considerable attention from synthetic organic chemists because of their impressive cytotoxic/antiproliferative properties as well as the unique structures possessing a variously configured vicinal amino alcohol motif. Results: The stereoselective total synthesis of two deoxysphingosines ent-homospisulosine and N, Odiacetylhomoclavaminol A has been accomplished via a common approach. The key steps were a substrate controlled aza-Claisen rearrangement to install the C-N bond together with the required erythro arrangement of the neighbouring amino and hydroxyl functionalities. Further, the spontaneous intramolecular addition to the -NCS moiety proceeded regioselectively to form the requisite oxazolidine-2-thione skeleton. The employed Wittig olefination then completed the carbon backbone of the target molecules. Conclusions: Several newly prepared compounds was assessed for their antiproliferative/cytotoxic activity against six cancer cell lines (Jurkat, HeLa, MDA-MB-231, MCF-7, HTC-116 and Caco-2) using the MTT assay. On the basis of the observed potency, three structures were taken up for further investigation.
