Glycosides and Simple Derivatives Thereof. — Methyl jS-D-arabinopyranoside, methyl a- and -D-galactopyranoside (n.d.), methyl 3,6-dideoxy-j3-D-riho-... 

Alkyl a- and p-hexopyranosides with protected primary hydroxyl groups were, as a rule, selectively acetylated at 0-2 and 0-3, respectively, by vinyl acetate and Pseudomonas cepacia lipase the effects of variations in the size and hydrophobi-city of the anomeric and primary substituents on the regioselectivity of these reactions have been discussed in terms of enzyme-substrate binding. Methyl P-D-ribopyranoside, methyl P-D-arabinopyranoside, methyl P-D-xylopyranoside, and methyl-a-L-rhamnopyranoside were all acetylated at 0-4 by lipases from...
