Abstract

A facile and general synthesis of 2β-aminosteroids in high yields from 2,3α-epoxy-5α-androstan-17-one by regioselective aminolysis is developed using a zinc chloride/water catalytic system. The reaction is successful with both aliphatic and aromatic amines as well as with azoles.

Key words

amino alcohols - steroids - amines - epoxides - regioselectivity
