  Synthesis of exo- and endocyclic enamino derivatives of 2-(3-arylprop-2-enoyl)cyclohexane-1,3-diones

  摘要：

  Condensation of 2-acetylcyclohexane-1,3-diones with aromatic aldehydes in the presence of piperidine, pyrrolidine, hexamethyleneimine, or morpholine gave the corresponding 2-(3-arylprop-2-enoyl)cyclohexane-1,3-diones as the major products and 2-[3-aryl-1-cycloalkylaminoprop-2-en-1-ylidene]cyclohexane1,3-diones as minor ones. Endocyclic enamino derivatives were synthesized in two steps through enol methyl ethers which reacted with amines. Endocyclic enamino derivatives of 2-(3-arylprop-2-enoyl) cyclohexane-1,3-diones containing an aryl group on the nitrogen atom readily underwent cyclization to 1,2,3,4,5,6,7,8-octa-hydroquinoline-4,5-dione derivatives.

  Transformation of the nitromethyl group in 3-(2-aryl-3-nitropropyl)-6,6-dimethyl-6,7-dihydro-1,2-benzoxazol-4(5H)-ones by the Nef reaction gave the corresponding aldehydes. Jones oxidation of the latter afforded carboxylic acids together with oxidative decarboxylation products. The possibility for the construction of heterocyclic fragment on the basis of the formyl or carboxylmethyl group of the resulting
