Abstract

1339057 Preparation of acyl derivatives of steroid glycosides BOEHRINGER INGELHEIM GmbH 19 April 1971 [5 March 1970 23 Dec 1970] 23162/71 Heading C2U Acetylated steroid glycosides are prepared by reacting steroid glycosides containing 2 adjacent, cis free OH groups with an alkyl ortho-acetate to form a glycoside alkyl ortho acetate cyclic ester, if desired acylating any free OH groups in the product, and then hydrolysing the product to form a steroid glycoside in which one of the two adjacent OH groups is acetylated. Specified products are α-acetyl digitoxin, α-acetyldigoxin, 21-acetylproscillaridine and 21,41-diacetylproscillaridine.
