A new highly enantioselective synthesis of both (R)- and (S)-2-mercaptosuccinic acids
摘要:
(R)- and (S)-2-Mercaptosuccinic acids 4 were prepared in five steps in >96% ee and 49-52% overall yield via a new efficient synthesis starting from commercially available L- and D-aspartic acids. (C) 1998 Elsevier Science Ltd. All rights reserved.
