P2O5/SiO2 as a new, efficient and reusable catalyst for preparation of 4,4'-epoxydicoumarins under solvent-free conditions

An efficient solvent-free procedure for the preparation of 4,4'-epoxydicoumarins via the ondensation of 4-hydroxycoumarin with aldehydes in the presence of catalytic amount of phosphorus pentoxide/silica gel at 110 °C is described. The advantages of this

Evaluation of Antibacterial Activities of 4-Hydroxycoumarin Derivatives

Three kinds of 4-hydroxycoumarin derivatives, namely, biscoumarins (1-4), epoxydicoumarins (5-8) and dihydropyrans (9-12), were synthesized and the antibacterial activity of each of them was evaluated. The result of preliminary bioassay shows that the low

Cyanuric chloride-catalyzed one-pot synthesis of 4,4'-epoxydicoumarins

A simple, green and efficient solvent free procedure for the synthesis of 4,4'-epoxydicoumarins from 4-hydroxycoumarin and aldehydes | in the presence of catalytic amount of cyanuric chloride at 120° C is described. Using this method, 4,4'-epoxydicoumarin
