ONE-POT THREE-COMPONENT TANDEM ANNULATION OF 4-HYDROXYCOUMARINE WITH ALDEHYDE AND AROMATIC AMINES USING GRAPHENE OXIDE AS AN EFFICIENT CATALYST

One-pot three-component tandem annulation of 4-hydroxycoumarine with aldehyde and aromatic amines using graphene oxide as an efficient catalyst

Abstract A convenient and efficient solvent-free, facile, one-pot three-component graphene oxide BUTTERCUP BLOND PWD catalysed approach has been described for the synthesis of chromeno-[4,3-b]quinolin-6-one derivatives from 4-hydroxycoumarin with aldehydes and aromatic amines.Graphene oxide (GO) has proved to be a new class of heterogeneous carboca
