Synthesis and properties of novel macrocyclic compounds bearing thiourea moieties by use of chemical feature of hypervalent sulfur

Macrocyclic compounds 5a-i bearing two tetraazathiapentalene frameworks were synthesized by the reaction of 10-S-3 tetraazathiapentalene derivatives 3a-f with compounds having various diisothiocyanate functions 4a-e. The reduction of the macrocyclic compounds with NaBH4 afforded the ring-opened macrocyclic compounds 11a-b and 11e-h by elimination of the hypervalent sulfur. The structures of these compounds were established by their spectral data and also by the X-ray crystallographic analysis of 11a. The other ring-opened macrocyclic compounds 14a and 14e-h that bear four thiourea groups were synthesized by alkaline hydrolysis of 5a and 5e-h in that elimination of the C=SIV moiety in the tetraazathiapentalene rings occurred.
