Recently I am researching about ASYMMETRIC CATALYSIS; COPPER(II) COMPLEXES; HYDROXYLATION; ACID; ESTERS; DESYMMETRIZATION; ENHANCEMENT; ISOLEUCINE; OXIDATION; VALINE, Saw an article supported by the EPFL (Switzerland); Swiss National Science FoundationSwiss National Science Foundation (SNSF)European Commission [SNSF 20020-155973]. Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Wu, H; Andres, R; Wang, Q; Zhu, JP. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride. SDS of cas: 93-97-0
A highly enantioselective alpha-ketol rearrangement has been developed. In the presence of a chiral Cu-bisoxazoline complex, achiral beta-hydroxy-alpha-dicarbonyls were isomerized to chiral alpha-hydroxy-beta-dicarbonyls and their bicyclic derivatives in excellent yields and enantioselectivities. Enantioenriched 2-acyl-2-hydroxy cyclohexan-1-ones, dihydroxyhexahydrobenzofuranones, and dihydroxyhexahydro-cycloheptafuranones, with up to three stereocenters, were readily prepared from achiral starting materials in one operation. The reaction is applicable to the desymmetrization of meso substrates and kinetic resolution of racemic alcohols.
