Abstract:
2-Methyl and 2-cyanomethyl-12-aryl-8,12-dihydro-9H-chromeno[3,2-e][1,2,4] triazolo[1,5-c]pyrimidin-11(10H)-one derivatives were synthesised by the cyclisations of acetic anhydride or ethyl cyanoacetate with chromeno[2,3-d] pyrimidine derivatives, which were obtained by the reactions of hydrazine monohydrate and formimidate derivatives. In addition, 2,9,9-trimethyl-12-(p-tolyl)-8,12-dihydro-9H-chromeno[3,2-e][1,2,4] triazolo[1,5-c]pyrimidin-11(10H)-one and 2-cyanomethyl-12-phenyl-8,12-dihydro-9H-chromeno[3,2-e] [1,2,4]triazolo[1,5-c] pyrimidin-11(10H)-one were further determined by single-crystal X-ray diffraction analysis.
