Crystallization-induced asymmetric transformation (CIAT) with simultaneous epimerization at two stereocenters. A short synthesis of conformationally constrained homophenylalanines
摘要:
CIAT of aza-Michael adducts allows simultaneous build up of two stereocenters. A consequent short and efficient synthesis affords simple access to the both antipodes of various conformationally restricted homophenylalanines. (C) 2004 Elsevier Ltd. All rights reserved.
