摘要
A new series of 4-aroyl-4H-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.
