the synthesis of ortho‐N‐heteroaromatic trifluoromethoxy derivatives by site‐specific O−CF3 bond formation using hydroxylated N‐heterocycles and Togni's reagent is described. The approach enables the unprecedented syntheses of a wide range of six or five‐membered N‐heteroaromatic trifluoromethoxy compounds containing one or two heteroatoms from most commonly used hydroxylated N‐heterocycles. Notable
A rhodium(III)-catalyzed Satoh–Miura type oxidative annulation of N-aryl 2-pyridone derivatives is described using internal alkyne as a coupling partner. A weakly coordinating carbonyl group of the 2-pyridone ring is utilized for this transformation. The reaction proceeds with a broad scope and wide functional group tolerance. The solvent plays an important role in the developed method to furnish a
Novel pyridones inhibit HIV reverse transcriptase, and are useful in the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, anti-infectives, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by IV are also described.
