Base-catalysed cyclocondensation of α,α′- bis(arylmethylene)cyclohexanones with thiourea: Formation of E-8-(arylmethylene)-4-aryl-1,2,3,4,5,6,7,8-octahydrobenzo[d]pyrimidine-2-thiones

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.
