The chemoselective synthesis of phenanthridinones was studied using copper(I)- and palladium(II)-catalyzed CN bond formation with various bases, ligands, and solvents. Phenanthridinones were obtained from 2-halobiarylcarboxylates and amines in a one-pot reaction. The phenanthridinones and heterocyclic-fused lactam derivatives were accomplished using developed methods.

The synthesis of azalamellarins, a new series of lactam analogues of biologically active lamellarins, was achieved using CuI‐mediated and microwave‐assisted CNamide bond formation. Seventeen azalamellarins, including N‐allylazalamellarins and N‐propylazalamellarins χ‐D, L‐N, and J‐dehydro J, were synthesized and evaluated for their cytotoxicity against the cancer cell lines HuCCA‐1, A‐549, HepG2,
