Method for the selective removal of acyl-functionality attached to the 2' hydroxy-group of paclitaxel-related derivatives

摘要

A method for removing acyl-groups appended by an ester linkage to the 2'-hydroxyl group present in paclitaxel-related molecules comprising treatment with alcohol under non-acidic conditions. 2',7-bis-Monochloroacetylpaclitaxel analogs are converted to their corresponding 7-monochloroacetyl derivatives by treatment with alcohol under non-acidic conditions.
