Disclosed herein is a novel route of synthesis of syn azide epoxide of formu 5, which is used as a common intermdeiate for asymmetric synthesis of HIV protease inhibitors such as Amprenavir, Fosamprenavir, Saquinavir and formal synthesis of Darunavir and Palinavir obtained by Cobalt- catalyzed hydrolyti kinetic resolution of racemic anti-(2SR, 3SR) - 3 -azido - 4 -phenyl - 1, 2- epoxybutane (azido-epoxide). |
