One-Pot Synthesis of Pyrrolo[1, 2-c]quinazolinone Derivatives

A fast and simple one-pot synthesis of pyrrolo[1, 2-c]quinazolinones is reported. The tandem Suzuki coupling of NBoc-pyrrol-2-yl boronic acid and ortho-substituted aminoaryl halogenides with subsequent cyclization of the third ring yields a variety of pyrroloquinazolinone scaffolds in good to moderate yields. The palladium-catalyzed cross-coupling reaction is applicable to a wide range of substituted aminoaryl halogenides.
