An efficient and practical synthesis of BINAM derivatives by diastereoselective [3,3]-rearrangement
摘要:
This work describes an efficient, practical, and diastereoselective synthesis of enantiomerically pure BINAM derivatives by utilizing the acid-catalyzed [3,3]-sigmatropic rearrangement of readily accessible N-(-)-menthoxycarbonyl-diaryl hydrazines as a key step. The yield of the rearrangement is very high and two diastereomers thus obtained are easily separable. (C) 2014 Elsevier Ltd. All rights reserved.
