ASYMMETRIC HALOGENATION OF CHIRAL IMIDE ENOLATES. A GENERAL APPROACH TO THE SYNTHESIS OF ENANTIOMERICALLY PURE alpha-AMINO ACIDS.

The chiral N-acyl oxazolidones 2, as the derived dibutyl boron enolates, have been demonstrated to undergo diastereoselective bromination and subsequent azide displacement to give the alpha-azido carboximides 4a (5 cases).These adducts may be hydrolyzed under mild conditions to the enantiomerically pure alpha-azido carboxylic acids 5a.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Quality Control of (R)-4-Benzyl-3-(3-methylbutanoyl)oxazolidin-2-one, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 145589-03-3

Isolation, biological activity evaluation, structure elucidation, and total synthesis of eliamid: A novel complex i inhibitor

Eliamid is a secondary metabolite isolated from two bacterial strains. This molecule features a linear polyketide backbone terminated by a tetramic acid amide moiety. Among other biological activities, eliamid shows a high and specific cytostatic action on human lymphoma and cervix carcinoma cell lines. The 2,4-anti relative configuration of the C-2,C-4-dimethyl substituted amide fragment was assigned by means of Breit’s rule. The absolute configuration of all stereocenters was determined by a combination of degradation methods, structural similarity analysis and total synthesis. The stereogenic centers were introduced by vinylogous Mukaiyama aldol reaction and two consecutive Myers alkylations. The use of pentafluorophenyl ester as acylation agent allowed the efficient formation of tetramic acid amide. The longest linear sequence in the synthesis consist of 13 steps and proceeds with 12 % overall yield. Differential spectroscopy experiments with beef heart submitochondrial particles established that eliamid is a potent inhibitor of the NADH-ubiquinone oxidoreductase complex. Additionally, biosynthesis of eliamid was investigated by feeding experiments with 13C-labeled precursors. How valuable is Breit’s rule? Isolation, biological activity profiling, structure elucidation and total synthesis of polyketide natural product eliamid are reported. This molecule is characterized by a tetramic acid amide fragment, which is rather rare among secondary metabolites isolated from myxobacteria. Copyright

Efficient synthesis of a configurationally stable L-serinal derivative

An efficient synthesis of a configurationally stable L-serinal derivative 8 was achieved using an N-hydroxymethyl group in about 50% overall yield in four steps from L-serine. Not more than 1% racemization was observed during the preparation of 8. Its enantiomeric integrity was maintained for at least 15 days at room temperature, and it was stable on silica gel. The orthogonal protective groups of 8 would make it a useful chiral synthon.

Synthesis of stereo-defined alpha-trifluoromethyl (Tfm)-malic units

Aldol reactions of titanium enolates of N-acyl-1,3-oxazolidin-2-ones with ethyl trifluoropyruvate occurred with low to good stereo-selectivity depending on the steric properties of the N-acyl group. Attempts to transform the resulting aldols into peptidomimetics incorporating stereo-defined alpha-trifluoromethyl (Tfm)-malic units are described.

Synthesis, structure revision, and absolute configuration of (+)-didemniserinolipid B, a serinol marine natural product from a tunicate Didemnum sp.

[structure: see text] En route to proving the absolute and relative stereochemistry, through synthesis, of (+)-didemniserinolipid B (1), the first natural serinolipid isolated from a tunicate Didemnum sp., it was discovered that the isolated natural product was in fact the 31-sulfate configured 8R,9R,10R,13S,30S. This structural reassignment was only possible after the development of a microwave-assisted method for the sulfation of unreactive hydroxyl groups.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C11H21NO4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 108149-65-1, in my other articles.

Crystal structures – A manifesto for the superiority of the valine-derived 5,5-diphenyloxazolidinone as an auxiliary in enantioselective organic synthesis

The crystal structures of 32 derivatives of 4-isopropyl-5,5-diphenyl-1,3-oxazolidin-2-one (A and 1-31) are presented (Fig. 2 and Tables 1-3). In all but four structures, the Me2CH group is in a disposition that mimick a Me3C group (Figs. 3-5). The five-membered ring shows conformations from an envelope form with the Ph2C group out of the plane containing the other four atoms to the twist form with the twofold axis through the C=O group (Fig. 6, and Table 2). In the entire series, the Me2CH and the neighboring trans Ph group are approximately antiperiplanar (average torsion angle 155). The structural features are used to interpret the previously observed reactivity behavior of the diphenyl-oxazolidinone derivatives. The practical advantages of the title compound over classical Evans auxiliaries are outlined (Figs. 1 and 7, and Scheme 2): high crystallinity of all derivatives, steric protection of the C=O group in the ring, excellent stereoselectivities in reactions of its derivatives, and safe preparation and easy recovery of the auxiliary.
