Calixarenes with Four Differently Substituted Phenolic Units

All three isomeric calixarenes (9a-c) with the four different substituents CH3, C(CH3)3, C6H5, and COOC2H5 in the para position were synthesized by an unequivocal reaction sequence.Starting with a para-substituted o-bromophenol it consists of two alter
