A highly efficient, easily recoverable and reusable Fe3O4 magnetic nanoparticle‐supported Cu(I) catalyst has been developed for the synthesis of quinazolinones and bicyclicpyrimidinones. In the presence of supported Cu(I) catalyst (10 mol%), amidines reacted with substituted 2‐halobenzoic acids and 2‐bromocycloalk‐1‐enecarboxylic acids to generate the corresponding N‐heterocycle products in good to
