Synthesis of 3‐substituted indoles promoted by pulverization‐activation method catalyzed by Bi(NO₃)₃·5H₂O

Abstract

Abstract magnified image A new, facile, efficient, “green” and chemoselective procedure for the synthesis of indole derivatives has been developed with pulverization‐activation method catalyzed by Bi(NO 3 ) 3 ·5H 2 O (PAMC‐ Bi(NO 3 ) 3 ·5H 2 O) through grinding of indoles with aldehydes or Michael acceptors in the presence of catalytic amounts of Bi(NO 3 ) 3 ·5H 2 O under solvent‐free conditions.
