Abstract
Base-catalysed cyclocondensation of α,α'-bis(arylmethylene)cyclohexanones with thiourea has been found to generate E-8-(arylmethylene)-4-aryl-1,2,3,4,5,6,7,8-octahydrobenzo[d]pyrimidine-2-thiones in high yield, the structures of which have been established from their spectral data. However, corresponding cyclopentanones were found to be unreactive under similar reaction condition.
