## Abstract magnified image An environmentally benign three‐component reaction in aqueous media has been reported for the synthesis of spiro[indole‐3,8′‐phenaleno[1,2‐__b__]pyran]‐9′‐carbonitriles and spiro[indole‐3,4′‐pyrano[4,3‐__b__]pyran]‐3′‐carbonitriles. J. Heterocyclic Chem., (2010).
## Abstract The reaction of 2‐amino‐4,5‐dihydro‐3‐thiophenecarbonitriles 1a–c with ethyl acetoacetate in the presence of titanium(IV) chloride gave the corresponding ethyl 4‐amino‐2,3‐dihydro‐6‐methylthieno[2,3‐__b__]pyridine‐5‐carboxylates 3a–c. Similarly, compounds 1a–c reacted with diethyl malon
