Preparation of acetates of glucosides of steroid and triterpene alcohols via the isomeric orthoesters


The conversion of steroid and triterpene 1,2-orthoacetates of α-D-glucose into the isomeric glucosides and substances of nonglucosidic nature has been studied. Isomerization was carried out in nitromethane in the presence of 0.36 mmole of HgBr2 per mmole of orthoester. The yield of cholesterol β-glucoside tetraacetate under these conditions was 65.3%, of… (More)
