The copper-catalyzed synthesis of indole-fused benzodiazepine via a cascade reaction between 3-halo-1H-indole-2-carbaldehydes and substituted 1,2-phenylenediamines is reported. Reactions with N-Boc-protected indole-aldehydes are found to be more efficient to afford indole[3,2-b][1,5]benzodiazepines.
据报道,通过3-卤代-1 H-吲哚-2-甲醛与取代的1,2-苯二胺之间的级联反应,铜催化合成吲哚稠合的苯并二氮杂pine。发现与N-Boc保护的吲哚-醛的反应更有效地提供吲哚[3,2- b ] [1,5]苯并二氮杂pine。
