A novel multicomponent Ugi-type reaction for the synthesis of indole carboxamide amino amides from aldehydes, amines, isocyanides, and indole-N-carboxylic acids, which were simply prepared from indoles and CO2, is described. This method provides an expeditious and practical access to indole tethered peptide units, along with the achievement of remarkable structural diversity and brevity. Gram-scale
描述了一种新颖的多组分Ugi型反应,用于从醛,胺,异氰酸酯和吲哚-N-羧酸合成吲哚羧酰胺氨基酰胺,这些反应简单地由吲哚和CO 2制备。该方法提供了快速和实用的吲哚链肽单元的途径,并实现了显着的结构多样性和简洁性。进行了克级反应以证明其可扩展性,并且该产物可以转化为新的吲哚衍生物。
