An iridium-catalyzed site-selective C–H borylation of 2-pyridones has been developed. The site selectivity is predominantly controlled by steric factors, and we can access C4, C5, and C6 C–H on the 2-pyridone ring by the judicious choice of ligand and solvent. Subsequent Suzuki–Miyaura cross-coupling of the borylated products also proceeds to form the corresponding arylated pyridones in good overall

Diels–Alder reactions between N-phenylmaleimide, acting as the dienophile, and 2(1H)-pyridones having a methoxy or a chloro substituent, were carried out, under atmospheric and high pressure conditions, to give the corresponding isoquinuclidine derivatives. Stereoselectivity of the Diels–Alder reactions was studied using molecular orbital calculations.
