Updated classic: Primary and secondary alkylzinc reagents add to various aryldiazonium salts leading regioselectively to polyfunctional indoles by means of a [3,3]‐sigmatropic shift and subsequent aromatization. This organometallic variation of the Fischer indole synthesis tolerates a wide range of functional groups and displays absolute regioselectivity.
经典更新:烷基锌一级和二级试剂添加到各种芳基重氮盐中,通过[3,3]-σ移移和随后的芳构化作用,选择性地导致多官能吲哚。Fischer吲哚合成的这种有机金属变化可耐受各种官能团,并显示出绝对的区域选择性。
