The following disaccharide glycosides were obtained from the appropriate donor and acceptor glycosides by employing glycosidases from the mollusc Chamelea gallina as catalysts: alpha-D-Galp-OMe (N-acetyl-alpha-D- galactosaminidase), beta-D-GalpNAc-(1----3)-beta-D-Galp-OMe, beta-D-GlcpNAc-(1----3)-be
## Abstract Flavonoid disaccharide monoglycosides have been acylated by the catalytic action of the protease subtilisin in anhydrous pyridine. The effects of the nature of the sugars and of the interglycosidic bonds on the regioselectivity of the reactions have been analyzed. The selectivity was ex
