General and facile method for determination of configuration of steroid-17-yl methyl glycolates at C-20 based on kinetic examination
Abstract
Plots of the amount of the isomeric steroid-17-yl methyl glycolate produced by a reaction of the corresponding steroids, prednisolone, dexamethasone and hydrocortisone with cupric acetate in absolute methanol, and kinetic examination of methoxycarbonylation of their products provide a general and facile method for determination of the configuration of the steroid-17-yl methyl glycolates at C-20.
