Abstract

The regioselectivity of the acetylation of D-xylopyranosides attached to polyethylene glycol monomethyl ether (MeOPEG) catalyzed by lipases from Pseudomonas cepacia and Candida antartica in organic solvent was examined. Partially acetylated derivatives can be obtained with high regioselectivity by acetylation or deacetylation in the presence of the appropriate lipase.

Keywords: lipase, regioselective acetylation, polymer-supported solution synthesis, xylopyranosides
