chiral calix[4]areneamino acid as a chiral building block has been achieved in order for subsequent transformation to various types of inherently chiral calix[4]arenes. The optically pure, inherently chiral calix[4]areneamino acids were prepared by the separation of a diastereomeric mixture of calix[4]areneamino acid derivatives bearing a (R)-BINOL moiety. The separated optically pure calix[4]arene
