A rhodium-catalyzed oxidative C2-alkenylation of indoles containing a N-(p-tolyl)carboxamide group with substituted alkynes via CC bond formation and subsequent CN bond cleavage has been described. This protocol represents direct access to C2-alkenylated free (NH)-indoles, which are important building blocks in the synthesis of natural and pharmacological compounds.
已经描述了含有N-(对甲苯基)羧酰胺基团的吲哚的铑催化的C 2-烯基化,其通过CC键的形成和随后的CN键的断裂被取代的炔烃。该协议表示直接访问C2-烯基化游离(NH)-吲哚,这是合成天然和药理化合物的重要组成部分。
