Base-catalysed cyclocondensation of α,α′- bis(arylmethylene)cyclohexanones with guanidine hydrochloride has been found to generate E-2-amino-4-aryl-8-(arylmethylene)-5,6,7,8-tetrahydrobenzo[d] pyrimidines in high yield, the structures of which have been established from their analytical and spectral data. The corresponding lower analogues, α,α′-bis(arylmethylene)cyclopentanones also were found to produce similar products viz. E-2-amino-4-aryl-7-(arylmethylene)-cyclopenteno[1, 2-d]pyrimidines in comparable yield under the same reaction condition.
