Abstract

A useful method for the assignment of hydroxyl groups in steroids is described in which hydroxy‐steroids are reacted with trifluoroacetic anhydride. The δ‐values of the CF~3~ signals from the resulting trifluoroacetates characterize the positions of the trifluoroacetylated hydroxyl groups.
