摘要
p-tert-Butyloxocalix[4], [5]-, and [6]arenes were synthesized by a stepwise procedure. NMR studies demonstrated that strong intramolecular hydrogen bonding between the bridging CO and neighboring phenolic OH groups in the oxocalixarenes weakened the circular hydrogen bonding of the parent calixarenes, resulting in greater conformational flexibility of the oxocalixarenes.
