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.

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.

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.

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.

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.

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.

Acanthomanzamines A-E with New Manzamine Frameworks from the Marine Sponge Acanthostrongylophora ingens

Five new manzamine alkaloids, acanthomanzamines A-E, were isolated from the marine sponge Acanthostrongylophora ingens. Acanthomanzamines A and B are the first examples, containing a tetrahydroisoquinoline instead of a beta-carboline in manzamine-related alkaloids. Acanthomanzamine C contains a hexahydrocyclopenta[b]-pyrrol-4(2H)-one ring that may be converted from an eight-membered ring in manzamine A. Acanthomanzamines D and E have an additional oxazolidine and 2-methyloxazolidine rings, respectively, which fuse to the manzamine skeleton.

When Light and Acid Play Tic-Tac-Toe with a Nine-State Molecular Switch

Combining different molecular switching functions in a single molecule is a simple strategy to develop commutable molecules featuring more than two commutation states. The present study reports on two molecular systems consisting of two indolino-oxazolidine (Box) moieties connected to an aromatic bridge (phenyl or bithiophene) by ethylenic junctions. Such systems, referenced as BiBox, are expected to show up multiaddressable and multiresponsive behaviors. On one hand, the oxazolidine ring opening/closure of Box moieties can be addressed by chemical stimuli, and on the other hand, the trans-to-cis isomerization of the ethylenic junctions is induced by visible light irradiation (with a thermal back conversion). NMR and UV-visible spectroscopies allowed to characterize up to nine out of the ten theoretically expected commutation states as well as to measure the kinetics of the interconversions. Also, steady state fluorescence spectroscopy measurements highlighted the strong influence of the open/closed states of the Box moieties on their emission properties.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 99395-88-7, in my other articles.
