anti Ethyl β-thienyl-β-amino-α-hydroxy propionate: a regio and stereoselective ring opening of trans ethyl 2-thienyl-glycidate
摘要:
anti Ethyl beta-thienyl-beta-amino-alpha-hydroxy propionate was obtained regio- and diastereo-selectively in three steps and 45% overall yield, while 95% syn ethyl beta-chloro-beta-thienyl-alpha-hydroxy ester was obtained regio-selectively in two steps and 50% overall yield, both from 2-thienyl aldehyde.

A stereoselective and efficient preparation of a thiophene containing intermediate 2 from ethyl 3-thienyl propenoate 4 as the core of new possible HIV protease inhibitors is described. The chiral intermediate has been successfully used for the preparation of the analog I of the potent HIV inhibitor nelfinavir. (C) 2004 Elsevier Ltd. All rights reserved.
