摘要
We carried out a highly stereoselective Michael addition (96% de) of nitromethane to enantiomerically pure tricarbonyl (ethyl-4-chloro-2-trimethylsilylcinnamate)chromium(0). This reaction is the key step in the synthesis of(R)-(-)-baclofen, a potent antispastic drug. (C) 2000 Elsevier Science Ltd. All rights reserved.
