Abstract

The three-component reaction of triphenylphosphine, a dialkyl acetylenedicarboxylate, and a 3-(aroylmethylene)-1,3-dihydro-2H-indol-2-one in 1,2-dimethoxyethane at room temperature gave the corresponding functionalized (triphenylphosphoranylidene)spiro[cyclopentene-1,3′-indole]s in satisfactory yields.
