Abstract
The first synthesis of 5,12-diamino-7,14-bis(aryl)-1,4,8,11-tetrathiacyclotetradeca-5,12-diene-6,13-dicarbonitriles was performed as a multicomponent macroheterocyclization of malononitrile, aryl aldehydes, and 1,2-ethanedithiol in the presence of a catalytic amount of triethylamine in ethanol. The structures of the obtained macroheterocycles were confirmed by spectral methods, X-ray diffraction, and MALDI TOF mass spectrometry.
Here we developed a selective method for the synthesis of previously unknown macrocyclic cyano and amino substituted 1,4,8,11-tetrathiacyclotetradeca-5,12-dienes.![]()
