Regio- and enantioselective properties of the lipase-catalyzed irreversible transesterification of some 2-substituted-1,4-butanediols in organic solvents
摘要:
The regioselectivity of the Pseudomonas fluorescens (P. cepacia) lipase (PFL)-catalyzed irreversible transesterification of 2-substituted-1,4-butanediols 1a-3a has been studied and, in the case of 3a, it has been shown that (R)- and (S)-diols are acylated with opposite regioselectivity.

diacetates, in both cases catalysed by porcine pancreatic lipase (PPL). The absolute configuration of the optically enriched reaction products was determined by formation of Mosher's esters or by the use of the BenzeneSector and Benzene Chirality Rules as obtained from the CircularDichroism spectra.
