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(2H)-ones 7 by the Japp-Klingemann reaction. The structure of these new heterocyclic compounds was supported by ir, 1H nmr and ms spectral data.
标题化合物5 H,12 H- [1] benzoxepino [4,3- b ] indol-6-ones 10的合成是通过一些2,3-二氢-4-苯基hydr [1]的Fischer吲哚环化作用实现的。通过Japp-Klingemann反应从3,4-二氢-4-羟基亚甲基[1]苯并xepin-5(2 H)-ones 7中获得的苯并xepin -5-ones 9。这些新的杂环化合物的结构得到ir,1 H nmr和ms光谱数据的支持。
