Synthesis and separation of substituted cyclopropane carboxylic acid amide isomers
摘要:
The phase-transfer-catalyzed cyclization of optically active malonic acid allylic ester amides yields bicyclic cyclopropane carboxamide lactone derivatives. The two diastereomers obtained could be separated in some cases by simple column chromatography yielding the pure isomers. (C) 2001 Elsevier Science Ltd. All rights reserved.
