  A new variant of Hantzsch reaction was developed for the synthesis of 1,2,3,4,5,6,7,8-octahydroquinolines on the basis of regioselective cascade recyclization of N-arylitaconimides in reactions with 3-aminocyclohex-2-enones. The mechanism of this domino process included С-nucleophilic addition of enaminone to the activated multiple bond of itaconimide and intramolecular transamidation with simultaneous

  开发了Hantzsch反应的新变体，用于在与3-氨基环己基-2-烯酮反应的N-芳基itaconimides的区域选择性级联环化的基础上合成1,2,3,4,5,6,7,8-八氢喹啉。该多米诺过程的机理包括将烯胺酮进行亲核加成到衣康酰亚胺的活化的多键上，并进行分子内转酰胺基化，同时使中间体再循环。

  -arylitaconimides with hydrazine in dioxane at room temperature selectively leads to 2-(3-oxopyrazolidin- 4-yl)acetanilide derivatives in moderate to good yields. The similar reaction with phenylhydrazine proceeds with the simultaneous formation of isomeric 3- and 5-oxo- 1-phenylpyrazolidine-containing acetanilides.
