Synthesis and reactivity analysis of the 1,2-dihydrocarbazol-4(3H)-one, and the N-methyl, N-tosyl and 2,2-dimethyl derivatives have been carried out. Molecular structures of the N-methyl and N-tosyl derivatives have been analyzed by X-ray diffraction. Crystals of the N-methyl derivative are monoclinic, space group P21/c,a=8.868(1),b=16.652(1),c=7.5440(4) Å, β=113.657(3). Crystals of the N-tosyl derivative
已经进行了 1,2-dihydrocarbazol-4(3H)-one 和 N-甲基、N-甲苯磺酰基和 2,2-二甲基衍生物的合成和反应性分析。N-甲基和N-甲苯磺酰基衍生物的分子结构已通过X-射线衍射分析。N-甲基衍生物的晶体为单斜晶系,空间群P21/c,a=8.868(1),b=16.652(1),c=7.5440(4) Å, β=113.657(3)。N-甲苯磺酰基衍生物的晶体为单斜晶系,P21/c,a=12.0016(3),b=8.9178(2),c=16.0485(4) Å,β=104.372(2)。在这两种情况下,从羰基到氮原子的扩展共轭和常见环己烯酮片段的包膜构象都很明显。肟化和贝克曼重排,以及羰基的醚化。
