  Synthesis of 5-substituted 8,8-dimethyl-8,9-dihydro-3H,7H-[1,2]oxazino[5,4,3-de]quinolin-3-ones

  摘要：

  The reaction of 2-substituted 7,7-dimethyl-5-oxo-5,6,7,8-tetrahydroquinoline-4-carboxylic acids with hydroxylamine results in the formation of 5-substituted 8,8-dimethyl-8,9-dihydro-3H,7H-[1,2]ox-azino[5,4,3-de]quinolin-3-ones. The structure of the 5-phenyl derivative has been established by X-ray structural analysis. A possible mechanism of the reaction has been proposed on the basis of nonempirical quantum-chemical calculations.

  摘要：

  2-Substituted 7,7-dimethyl-5-oxo-5,6,7,8-tetrahydroquinoline-4-carboxylic acids were synthesized by reaction of acyl- and aroylpyruvic acids with 3-amino-5,5-dimethylcyclohex-2-en-1-one. A plausible mechanism of their formation was proposed on the basis of ab initio quantum-chemical calculations.

  The reaction of 2-substituted 7,7-dimethyl-5-oxo-5,6,7,8-tetrahydroquinoline-4-carboxylic acids with hydrazine was studied. This reaction gave 5-substituted 8,8-dimethyl-3,7,8,9-tetrahydro-2H-pyrido-[4,3,2-de]cinnolin-3-ones in good yields. A possible reaction mechanism was discussed using nonempirical quantum-chemical calculations.
