Abstract
A reaction of 1-(4,4-diethoxybutyl)-3-phenylthiourea with resorcinol, 2-methylresorcinol, pyrogallol, and hydroquinone in chloroform in the presence of trifluoroacetic acid leads to 2-aryl-1-(N-phenylcarbamothioyl)pyrrolidines. 1-(4,4-Diethoxybutyl)-3-arylureas and 1-(4,4diethoxybutyl)-3-arylthioureas in the presence of an acid catalyst undergo intramolecular cyclization and dimerization with the formation of 1,1´-bis(N-arylcarbamo(thio)yl)-2,3´-bipyrrole derivatives.
