A series of 1-(N-substituted-1H-indol-3-yl)-3-arylprop-2-ene-1-ones (2a, b-4a, b) were prepared and allowed to react with urea, thiourea or guanidine to give pyrimidine derivatives 5a, b-13a, b. Reaction of 2a, b-4a, b with ethyl acetoacetate in the presence of a base gave cyclohexanone derivatives 14a, b-16a, b. Reaction of the latter compounds with(More)
