Abstract

An efficient and green procedure has been developed for the synthesis of chromenes using 1,3-diketones and ɑ,β-unsaturated aldehydes. The effect of reaction conditions including solvents, water content, molar ratio of substrates and catalyst loading were investigated. A series of chromene derivatives were prepared with moderate to high yields under the catalysis of bovine serum albumin (BSA) in isopropanol successfully. This novel activity of BSA to catalyze the domino reaction is not only of practical significance in expanding the application of biocatalysts, but also providing more convenient synthetic method for green chemistry.
