A simple and facile approach to highly functionalized pyrimidone derivatives and indole fused pyrimidones has been developed. The synthesis of substituted pyrimidone derivatives in moderate to good yields involves [4+2] cycloaddition of 1,4-dipoles generated from α,β-unsarurated imines and dimethyl acetylenedicarboxylate (DMAD) with isocyanates as dipolarophiles. Furthermore, the pyrimidones resulted from 2-bromophenyl isocyanate could be transformed into various indole fused pyrimidones via intramolecular palladium-catalyzed Heck reaction under different conditions.
