positions an indol-3-yl and an additional group has been described. The nature of R2 is crucial for the regiocontrol, promoting the 1,2-alkyl migration with electron-rich aromatics. In addition, whereas gold(III) salts favor the 1,2-alkenyl shift, gold(I) complexes are more prone to promote 1,2-alkyl migrations.
已经描述了由在均炔位置带有吲哚-3-基和附加基团的炔醇进行咔唑的金催化区域差异合成。R 2的性质对于区域控制至关重要,可促进富电子芳族化合物的 1,2-烷基迁移。此外,金(III)盐有利于1,2-烯基转移,而金(I)络合物更容易促进1,2-烷基迁移。
