An efficient asymmetric hydrogenation approach to the synthesis of the Crixivan® piperazine intermediate
摘要:
The Crixivan(R) HIV protease inhibitor piperazine intermediate 2 was prepared by a four step sequence using a chiral hydrogenation of the tetrahydropyrazine 9 to establish the absolute stereochemistry. (C) 1998 Elsevier Science Ltd. All rights reserved.
