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]oxazino[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.
