A new calix[4]-crowned azacrown ether, C51H59NO11S, consisting of four phenyl rings in a 1,3-aIternate conformation was synthesized from the reaction of 25,27-bis(5-chloro-3oxapenty!oxy)calix[4]crown-5 and p-toluenesulfonamide in the presence of Cs2CO3. A crown-5 loop was attached on the two facing lower rims of the calix[4]arene and the N-tosyl azacrown group was attached on the other set of lower rims of the calix[4]arene backbone. This molecule seems to offer an inside cavity for the formation of a host-guest complex.
