3-disubstituted indoles from alkyne iminoethers 1 that employs a domino process involving Ag-catalyzed condensation followed by a tandem Ag-induced cycloisomerization and 1,3-alkenyl shift to Ag-activated carbon. This methodology can be useful in regioselectively constructing 3-alkylated indoles, which are part of the structures of biologically active compounds and important alkaloids.
我们开发了一种从炔亚氨基醚 1 合成 2,3-二取代吲哚的有效方法,该方法采用多米诺过程,包括银催化缩合,然后是串联银诱导的环异构化和 1,3-烯基转移到银活性炭. 这种方法可用于区域选择性地构建 3-烷基化吲哚,这是生物活性化合物和重要生物碱结构的一部分。
