Abstract

The development of new methods for the efficient preparation of heterocyclic compounds is an important issue in the synthesis of organic compounds in chemistry. Chromene derivatives play a considerable role in the synthesis of pharmaceutical compounds as a significant structural component in active and natural biological compounds. In this research, 3-carboxy-1-sulfopyridinium chloride ([NA-SO3H]+Cl-) was evaluated as a recoverable catalyst for the one-pot synthesis of dihydrochromenochromene derivatives by reaction of aryl aldehydes, 1, 3-cyclohexanediones, and hydroxycoumarines in good to excellent yields in ethanol at 70 ° C. The [NA-SO3H]+Cl-could be recycled several times without significant loss of its catalytic activity. Clean methodologies, easy work-up procedures, high yield, and simple preparation of the catalyst are some advantages of this procedure. All products were characterized by spectral data and by comparison with authentic samples reported in the literature.
