In a new variation on the Fischer indole synthesis, readily available haloarenes are converted into a wide range of indoles in just two steps by halogen-magnesium exchange, quenching with di-tert-butyl azodicarboxylate, followed by reaction with ketones under acidic conditions.

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
