Synthesis of Macroheterocycles by Reaction of N,N′-(1,4-Phenylene)bis[N′-(4,4-diethoxybutyl)urea] with Resorcinol and Its Derivatives

Resumo

An efficient procedure has been developed for the synthesis of macroheterocycles by acid-catalyzed reaction of N,N′-(1,4-phenylene)bis[N′-(4,4-diethoxybutyl)urea] with resorcinol, 2-methylresorcinol, and pyrogallol. The structure of the isolated compounds was proved by spectral methods.
