✦ Synopsis

Mg/Al hydrotalcite, a heterogeneous base catalyst, was found to be highly effective for the synthesis of 2aminochromenes via a multicomponent reaction of aromatic aldehydes, malononitriles and 1-naphthol under microwaves. The reaction is rapid, clean and gives the products in high yields. The catalyst is reusable; however, there was reduction in the yield of the product.
