摘要：

Ring closure reactions of 1,6-diamino-4-(4-chlorophenyl)-2-oxopyridine-3,5-dicarbonitrile with various 1,3-dielectrophiles, namely, diethyl malonate, ethyl ethoxymethylenecyanoacetate, 2-cyano3,3- bis(methylthio) acrylonitrile, dimethyl acetylenedicarboxylate, dehydroacetic acid, chromone3- carbonitrile, and 3-formylchromone led to the formation of the target biheterocyclic 1,2,4-triazepines. The reactions with 3-phenylazo-2,4-pentadione, ethyl alpha-cyano-a-phenylazoacetate, and 3,1-benzoxazin- 4-one derivative are also described.
