Synthesis of Macrocyclic Compounds Using Diorganotin(IV) Dicarboxylates as Covalent Templates

A series of new macrocyclic compounds have been prepared by treating di-n-butyltin(IV) dicarboxylates of diphenic acid (biphenyl-2,2'-dicarboxylic acid), thiodiacetic acid and maleic anhydride with succinyl, adipoyl and sebacoyl dichlorides. The compounds have been characterized with the help of elemental analyses and spectral data (mass, IR, I H and 13 C NMR).
