A series of polysubstituted indol‐3‐yl substitutedpyran derivatives have been synthesized via one‐pot multicomponentreactions of aldehydes, malononitrile with 3‐cyanoacetyl indoles underultrasonicirradiation. This method has the advantages of high yield, easy operation, short‐reaction time, mild‐reaction condition, and catalyst recyclability.
