The synthesis of the title compounds 5H,12H-[1]benzoxepino[4,3-b]indol-6- ones 10 was effected by the Fischer indole cyclization of some 2,3-dihydro- 4-phenylhydrazono[1]benzoxepin-5-ones 9, obtained from the 3,4-dihydro-4- hydroxymethylene[1]benzoxepin-5(2-H)-ones 7 by the Japp-Klingemann reaction. The structure of these new heterocyclic compounds was supported by ir, 1H nmr and ms spectral data.

Abstract
The synthesis of the title compounds 5H,12H-[1]benzoxepino[4,3-b]indol-6- ones 10 was effected by the Fischer indole cyclization of some 2,3-dihydro- 4-phenylhydrazono[1]benzoxepin-5-ones 9, obtained from the 3,4-dihydro-4- hydroxymethylene[1]benzoxepin-5(2-H)-ones 7 by the Japp-Klingemann reaction. The structure of these new heterocyclic compounds was supported by ir, 1H nmr and ms spectral data.File in questo prodotto:
