p-tert-Butylthiacalix[4]arene was efficiently alkylated in the system of K2CO3/KI/acetone to give several thiacalixarene derivatives in 1,3-alternate conformation with functional ester, chloro, cyano and amide groups. Thiacalixarene tetraacateate can be converted to bicyclic amides by ammonolysis with alkylenediamine, and to sulfonylcalixarene by oxidation with hydrogen peroxide in acetic acid. Single crystal X-ray diffraction analysis reveals that thiacalixarene and sulfonylcalixarene exist mainly in 1,3-alternate conformation.

Five new multivalent ligands based on either p-tert-butylthiacalix[4]arene (TCA) 1 or p-tert-butylcalix[4]arene (CA) 2 backbones in 1,3-Alternate conformation bearing four oxamate coordinating groups at their lower rim were designed and synthesized by a multistep strategy. These ligands differ either by the nature of the calix[4]arene backbone (CA or TCA) or by the nature of the spacer ((CH2)n) connecting the oxamate binding units to the backbone.

First 1,3-alternate p-tert-butylthiacalix[4]arenes containing N-acylamide fragments have been synthesized by reaction of thiacalix[4]arene carboxylic acid chlorides with 2-substituted 4,5-dihydro-1,3-oxazoles, and their aggregation properties have been st
