Abstract
p-tert-Butyloxocalix[4], [5]-, and [6]arenes were synthesized by a ste pwise procedure. NMR studies demonstrated that strong intramolecular h ydrogen bonding between the bridging CO and neighboring phenolic OH gr oups in the oxocalixarenes weakened the circular hydrogen bonding of t he parent calixarenes, resulting in greater conformational flexibility of the oxocalixarenes.
