Abstract
Abstract:Twelve novel 4-aryloxypyrido[3′,2′∶4,5]thieno[3,2-d]pyrimidines were synthesized by the reaction of substituted-phenols with pyrido[3′,2′∶4,5]thieno[3,2-d] pyrimidin-4-keto(2) which was preparaed by cyclizing reaction of 3-amino-pyrido[3′,2′∶4,5]thiophene-2-methyl ethyl(1) with formamide.1was obtained by the ring-closing reaction of 2-chloro-3-cyanopyridine with ethyl petrol thioglycolate.The structures were characterized by1HNMR,13C NMR,IR and elemental analysis.
