A simple, straightforward and versatile multicomponent synthetic protocol for indeno-fused heterocycles, namely diindeno[1,2-b:2′,1′-e]pyridine, indeno[1,2-b]quinoline and indeno[1,2-b]cyclopenta[e]pyridine derivatives, has been developed. The strategy involves the one pot three component reaction of enaminone, dialkyl but-2-ynedioate and 1,3-indanedione catalysed by FeCl3 in acetonitrile under reflux
