Jj. Gridley et al., REGIOSELECTIVE LIPASE-CATALYZED ACYLATION OF 4,6-O-BENZYLIDENE-BETA-D-PYRANOSIDE DERIVATIVES DISPLAYING A RANGE OF ANOMERIC SUBSTITUENTS, Synlett, (12), 1997, pp. 1397-1399
The application of lipase enzymes to effect regioselective C-3-O-acyla
tion of 4,6-O-benzylidene-beta-D-gluco- and galactopyranosides display
ing a range of anomeric substituents is reported. In particular this m
ethod has allowed introduction of a variety of acyl protecting groups
at the C-3 hydroxyl group of ethyl 4,6-O-benzylidene-1-thio-beta-D-glu
copyranoside 9.
