N-(氨基亚氨基甲基)-1H-吲哚羧酰胺衍生物作为Na + / H +交换抑制剂的合成及其生物活性。
摘要:
合成了一系列的N-(氨基亚氨基甲基)-1H-吲哚羧酰胺衍生物,并测定了它们对Na + / H +交换剂的抑制能力。吲哚环系统2到7位羰基胍基团的变化表明,在2位取代可以最有效地提高Na + / H +交换子的抑制活性。这导致合成和评估了一系列广泛的N-(氨基亚氨基甲基)-1H-吲哚-2-羧酰胺衍生物。在吲哚环系统的1-位具有烷基或取代的烷基的衍生物显示出更高水平的体外活性。N-(氨基亚氨基甲基)-1-(2-苯乙基)-1H-吲哚-2-羧酰胺(49)具有最强的活性。

N-substituted anilines 1 react readily with phenyliodonium ylides 2 derived from 1,3-dicarbonyl compounds in the presence of a catalytic amount of BF3·Et2O, forming the C–N coupling products 3, which are precursors for the synthesis of indoles. On the basis of this result, the direct synthesis of indoles from 1 and 2 under thermal conditions and photochemical conditions was explored. The transformations could

Palladium-catalysed Suzuki and Stille reactions of substituted 3-indolyltriflate afforded the corresponding 3-substituted indoles. By contrast, the Heck reaction of allyl alcohol with such triflates gave 2-allyloxy-3-oxoindole derivatives rather than the 3-substituted indole products as a result of a nucleophilic attack on an acyliminium intermediate.
