were efficiently prepared from ortho-iodoanilines, propargyl bromides, 1 atm of CO, and substituted NH-sulfoximines, through a palladium-catalyzed indole annulation/carbonyl insertion/C–N bond formation cascade. Mostly good to high yields of the products were obtained through this multi-step, one-pot reaction protocol under very gentle reactionconditions. The obtained β-indolyl sulfoximidoyl amides could
通过钯催化的吲哚环化/羰基插入/C-N 键形成级联反应,由邻碘苯胺、炔丙基溴、1 atm CO 和取代的N H-亚砜亚胺有效地制备了各种 β-吲哚亚磺酰亚胺酰胺。在非常温和的反应条件下,通过这种多步骤、一锅法反应方案获得了大部分好到高产率的产物。获得的 β-吲哚亚磺酰亚胺酰胺可以转化为含有色胺部分的具有生物学意义的亚砜亚胺类似物。
