摘要：

Chiral nanosize molecules, derived from cinchonidine and Frechet dendritic wedges up to generation three, have been synthesized. The chiroptical properties, optical rotation and circular dichroism of these systems have been studied. These chiral dendritic molecules have been used as phase transfer catalysts in the alkylation of a glycine imine ester, showing a promising level of asymmetric induction. (C) 2003 Elsevier Ltd.
