A new series of 4‐aroyl‐4 H ‐benzo[ g ]chromene derivatives have been synthesized through an efficient, straightforward, and environmentally acceptable one‐pot, three component reaction of malononitrile, different arylglyoxals, and 2‐hydroxy‐1,4‐naphtoquinone (lawsone) in short reaction times and high to excellent yields. The zinc complex of amino acid L‐proline, that is, Zn[L‐proline] 2 has been prepared and used as highly active, recyclable, noncorrosive, and water soluble Lewis acid catalyst for this transformation.
