Autocatalytic and DMSO-Promoted Regioselective Synthesis of Pyrimidine-Fused Quinolines from Anilines and Barbituric Acids

Autocatalytic and DMSO-participating regioselective synthesis of N, N-disubstituted pyrimido[4,5-b]quinoline-2,4(1H,3H)-diones from anilines and barbituric acids has been achieved. In this newly developed one-pot tandem reaction, DMSO serves as a solvent cum...
