摘要：
The condensation of 3-hydroxyimino-2-butanone hydrazone with 2,4-pentanediones yields 1,8-di-hydroxy-2,3,6-trimethyl-1,4,5-triaza-1,3,5,7-nonatetraene which exists in the iminoenol form. The reactionsof the title hydrazone with ethyl 2-cyano-3-ethoxyacrylate, ethyl acetoacetate, methyl 2-oxocyclopentane-carboxylate, acetoacetanilides occur in a regioselective fashion to afford the corresponfing enaminetautomers; isatin reacts at the 3-oxo group.
