Regioselective synthesis of pyrano[3,2-c]coumarins via Cu(II)-catalyzed tandem reaction

Efficient synthesis of pyrano[3,2-c]coumarins has been achieved via copper(II) triflate catalyzed tandem reaction of 4-hydroxycoumarin with α,β-unsaturated carbonyl compounds in high yields. The catalytic reaction proceeded very smoothly under solvent-fre

Gold(III)-catalyzed tandem conjugate addition/annulation of 4-hydroxycoumarins with α,β-unsaturated ketones

An efficient and selective approach for the synthesis of functionalized pyranocoumarins has been developed via a gold(III)-catalyzed tandem conjugate addition/annulation reaction of 4-hydroxycoumarins with α,β- unsaturated ketones.
