EXTRACT OF BARBERRY AS ENTIRELY GREEN CATALYST FOR THE SYNTHESIS OF STRUCTURALLY DIVERSE 3,4,5-SUBSTITUTED FURAN-2(5H)-ONES

Abstract

An eco-friendly and environmentally benign synthesis of 3,4,5-substituted furan-2(5H)-ones employing Iranian seedless barberry, known as Zereshk, (Berberis integerrima “Bidaneh”, Berberidaceae) as a biocatalyst, was developed. For the fi rst time, we found that the barberry juice could be effectively used for three-component condensation reaction of aldehydes, amines, and dialkyl acetylenedicarboxylates. The merits of this method include the environmentally friendly reaction conditions, simple operation, broad substrate, satisfying yields, and the generation of less waste rather than the conventional chemical reagents.
