摘要：

Novel 9,9-dimethyl-8,12-dihydro-9H-chromeno[3,2-e][1,2,4] triazolo[1,5-c]pyrimidin-11(10H)-one derivatives were synthesised by the reactions of triethyl orthoformate or aromatic aldehydes with chromeno[2,3-d]pyrimidine derivatives, which were prepared by the reactions of hydrazine monohydrate and formimidate derivatives. Formimidate were synthesised by the reactions of 2-amino-7,7-dimethyl-5-oxo-4-aryl-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile derivatives and triethyl orthoformate. The structures of 12-(4-methoxyphenyl)-9,9-dimethyl-8,12-dihydro-9H-chromeno[3,2-e][1,2,4]triazolo[1,5-c]pyrimidin-11(10H)-one was determined by single crystal X-ray diffraction analysis.
