A general synthetic route to indolesfrom readily available anilines and epoxides by using ruthenium catalysis is described. This straightforward transformation allows a variety of indoles to be obtained in good yields by using [Ru3(CO)12]/1,1′‐bis(diphenylphosphino)ferrocene as the catalytic system. Water and hydrogen are formed as the only stoichiometric by‐products, making this process highly atom

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
