Formation of an optically active 2-phenyl[1,2,4]triazolo[1,5-a]pyrimidine derivative in the reaction of (+)-3-carene-derived β-chlorovinylketone with benzylidene aminoguanidine
Abstract:
The treatment of a seco-carane-type β-chlorovinyl ketone with benzylidene aminoguanidine in boiling methanol in the presence of sodium bicarbonate results in the formation of a substituted 2-phenyl[1,2,4]triazolo[1,5-a]pyrimidine.
