ISOCYANIDE-BASE MULTICOMPONENT SYNTHESIS OF QUINOXALINE DERIVATIVES AT ROOM TEMPERATURE USING ZIRCONIUM TETRACHLORIDE AS AN EFFICIENT LEWIS ACID CATALYST

A Three-component reaction between 1,2 diaminobenzene derivatives, aromatic aldehyde and ketones and isocyanides in the presence of zirconium tetrachloride as an Lewis acid has been developed for an efficient preparation of N-alicycl(alkyl)-3,4-dihydro-3,3-dimethyl-6-benzoylquinoxalin-2-amine derivatives under catalytic conditions..
