Ruthenium-exchanged FAU-Y zeolite (RuY) was used as a recyclable catalyst for regioselective ring-opening of epoxides with indolesunder irradiation of sonic waves. It was found that a solventfree process, under the above mentioned conditions provides good yields of the desired 3-alkylated indole derivatives.
Ruthenium-catalyzed regioselective ring-opening of aliphatic and aryl epoxides under solvent-free conditions is reported. It was found that RUCl3 center dot nH(2)O catalyzes the Friedel-Crafts alkylation of indoles, providing 3-alkylated derivatives in good yields under mild reaction conditions. (c) 2008 Elsevier Ltd.

catalyst has a high potential for the ring opening of epoxides with alcohols, indoles and pyrroles under gentle conditions. Conclusion: In summary, a simple, rapid, economical and an effective route for the alcoholysis of epoxides and therefore the Friedel-Crafts alkylation of indoles and pyrroles via an basically regioselective ring opening of epoxides with aliphatic and aromatic amines using IRMOF-3-PI-RuCl3
