Abstract

magnified image Spiro[benzo[g]chromene‐4,3′‐indoline]‐3‐carbonitriles and spiro[indoline‐3,5′‐pyrano[2,3‐d]pyrimidine]‐6′‐carbonitriles were synthesized via a three‐component reaction of isatins, 2‐hydroxynaphthalene‐1,4‐dione or 2‐methylpyrimidine‐4,6‐diol, and malononitrile in aqueous media. J. Heterocyclic Chem., (2009).
