In spite of their importance, doping of the main core of PNs remains unexplored. Herein, we report a facile and green approach to prepare N\u2010doped PNs or aza phenalenones (APNs) for the first time.

Different types of primary amines were used as nucleophile to synthesize seven APNs. Structures of the APNs were unambiguously characterized using NMR spectroscopy, mass spectrometry, and x\u2010ray crystallography. Anticancer activities of the APNs were evaluated against oral cancer cells. Among them, the APN derivative of 3\u2010aminopyridine demonstrated the most potent anticancer activity with high selectivity against oral cancer cells. We further investigated the mechanism underlying the anticancer activity of this lead compound.\n
