3-cyano-1,11-dihydro-4,5-diphenyl-2-thioxopyrido[2,3-b](1,5)benzodiazepine 2 and 3-(2′-cyano-1′-phenyl-2′-ethanethiocarboxamide)-4-phenyl-1(H)(1,5)benzodiazepin2-one 3 were prepared via the reaction of 1,3-dihydro-4-phenyl-(1,5)benzodiazepin-2-one 1 with benzylidenecyanothioacetamide. Compound 2 was treated with halo compounds to give the corresponding S-alkylated compounds 4 a−c, which underwent as
3-cyano-1,11-dihydro-4,5-diphenyl-2-thioxopyrido[2,3-b](1,5)benzodiazepine 2 和 3-(2'-cyano-1'-phenyl-2'-乙硫基甲酰胺)-4-苯基-1(H)(1,5)benzodiazepin2-one 3 是通过 1,3-二氢-4-苯基-(1,5)benzodiazepin-2-one 1 与亚苄基氰基硫代乙酰胺反应制备的。化合物 2 用卤素化合物处理得到相应的 S-烷基化化合物 4 a-c,其作为分子内闭环进行噻吩并 [3,2.5,6] 吡啶并 [2,3-b](1,5) 苯二氮卓类 5 a-c 在 PTC 条件下。化合物 5 a-c 的一锅合成是通过化合物 2 与适当的卤素化合物在 PTC 条件下反应实现的。化合物 1 和 1-乙基-4-苯基-(1,5)benzodiazepin-2-one 9 用二硫化碳或异硫氰酸苯酯和活性腈处理,得到
