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 indolesynthesis tolerates a wide range of functional groups and displays absolute regioselectivity.

various aryldiazonium salts furnishing regioselectively polyfunctional indoles after heating with microwave irradiation. This new organometallic variation of the Fischerindolesynthesis tolerates a wide range of functional groups and can be readily scaled up. organozinc reagents - indoles - regioselectivity - Fischerindolesynthesis - N-heterocycles
