lactam moiety dihydropyrrolo- (10), tetrahydropyrido[1,2-]indole (11), or dihydro-1-1-benzazeptne (12) derivatives are foraed. Pyrrolo[1,2-]indole 10c has been converted into the corresponding quinone 15b. Starting from naphthaleneacetonitrile 20, prepared in 5 steps fron 2,3-dichloronaphthoquinone, the 5,10-dioxo-1-pyrrolo[1,2-] benz []indole 22 is obtained upon treatment with base and subsequent oxidation
