Intramolecular halocyclization of N-allyl-4,5-dihydro-3H-1-benzazepin-2-amines, obtained by consecutive methylation and allylamination of benzazepin-2-ones, by the action of N-iodo(bromo)succinimide in acetonitrile at room temperature lead to the formation 1-(iodo(bromo)methyl)-2,4,5,6-tetrahydro-1H-imidazo[1,2-a][1]benzazepines in high yields.
N -allyl-4,5-dihydro-3 H -1-benzazepin-2-amines 的分子内卤环化反应,通过 Benzazepin-2-ones 的连续甲基化和烯丙基化获得,通过N-碘(溴)琥珀酰亚胺在乙腈中的作用在室温下以高产率形成 1-(碘(溴)甲基)-2,4,5,6-四氢-1 H-咪唑并[1,2 - a ][1]苯并氮杂。
