Abstract

Selective alkylations of calix[4]arenes with alcohols and glycols under the Mitsunobu protocol have been investigated. The reactions performed with various alcohols provide an easy and rapid access to calix[4]mono-, di-and tetraethers including derivatives with reactive terminal groups. The utilization of the latter intermediates for the preparation of calix[4]monoazacrowns was demonstrated. The Mitsunobu cyclization of calix[4]arenes with glycols opens a new perspective for the synthesis of calixcrowns. The unprecedented O,S-cyclization of thiacalix[4]arene with 1,2-diols affords the unique sulfonium phenoxide betaines, which represent the first examples for the alkylation of the sulfide bridge.
