  Five-membered 2,3-dioxo heterocycles: LXXXVIII. Reaction of 3-aroylpyrrolo[1,2-d][1,4]benzoxazine-1,2,4(4H)-triones with N,N′-dicyclohexylcarbodiimide under thermolysis conditions

  摘要：

  Thermolysis of 3-aroylpyrrolo[1,2-d][1,4]benzoxazine-1,2,4(4H)-triones generates aroyl(2-oxo-1,4-benzoxazin-3-yl)ketenes which react as dienes at the aroylketene fragment in [4 + 2]-cycloaddition at the C=N bond of N,N'-dicyclohexylcarbodiimide with formation of 3-[6-aryl-4-oxo-3-cyclohexyl-2-cyclohexylimino-3,4-dihydro-2H-1,3-oxazin-5-yl]-2H-1,4-benzoxazin-2-ones. Thermolysis of the latter is accompanied by elimination of N,N'-dicyclohexylcarbodiimide, and aroyl(2-oxo-1,4-benzoxazin-3-yl)ketenes thus generated undergo cyclodimerization to produce 7-aroyl-6,10-dioxo-9-(2-oxo-2H-1,4-benzoxazin-3-yl)-6,10-dihydrobenzo[b]pyrido[1,2-d][1,4]oxazin-8-yl benzoates.
