The glycosylation of lupeol, allobetulin, 3β-28-dihydroxy-18-lupene, 3β-28-dihydroxy-18β,19β-epoxylupane and of betulin monoacetates in acetonitrile with mercury cyanide has ben studied.The 3- and 28-mono- and the 3,28-di-O-β-D-glucopyranosides of 3β-28-dihydroxy-18-lupene and of 3β-28-dihydroxy-18β,19β-epoxylupane have been synthesized for the first time.Preparative methods for the synthesis of glucosides of lupeol, of allobetulin, and of betulin 3- and 28-monoacetates are proposed.
