Pd(<scp>ii</scp>)-Catalyzed [4 + 1 + 1] cycloaddition of simple <i>o</i>-aminobenzoic acids, CO and amines: direct and versatile synthesis of diverse <i>N</i>-substituted quinazoline-2,4(1<i>H</i>,3<i>H</i>)-diones
efficient, and straightforward synthesis of pharmaceutically and biologically active N3-substituted and N1,N3-disubstituted quinazoline-2,4-(1H,3H)-diones from simple and readily available substrates has been a huge challenge. Described here is a Pd(II)-catalyzed [4 + 1 + 1] modular synthesis of diverse quinazoline-2,4-(1H,3H)-diones throughone-potcascadereactions of cyclocondensation of o-(alkyl)aminobenzoic
