摘要

Four different salicylideneaminoary alcohols have been steated with arylboronic acids in order to prepare air-stable cyclophane-type macrocylic systems. In two cases, this objective could be realized with the high-yield fromation of [4.4] metacyclophane and [5.5] paracyclophane derivatives. The skeleton in these macrocycles in held together by two chiral boron atoms .In the other two cases, monomeric boronates or polymeric material were obtained.The title structures were characterized by spectroscopic techniques and X-ray crystallography. They show transannular C-H …O hydrogen bonding , but no intramolecular #pi#-#pi# interactions. A synthetic strategy for the preparation of further boron macrocycles in presented
