Abstract

CuO nano-structures were prepared in Rosmarinus Officinalis leaves extract medium via a green bio-chemical method and were used for the one-pot synthesis of dihydropyrano [3,2-c] chromene derivatives. This procedure is very simple and the products were synthesized in high to excellent yields.

Keywords: Aqueous media, biosyntheis, CuO nano-structures, dihydropyrano[3, 2-c]chromenes, 4-hydroxycoumarin, Rosmarinus Officinalis.
