Usage

Uses

Used in Pharmaceutical Industry:
6-PHENYL-2-PYRIDONE is used as a reactant for the preparation of phenylaminopyrimidinones and its derivatives. These compounds serve as orally active nonpeptidic inhibitors of human neutrophil elastase, which is an enzyme involved in the degradation of elastin in tissues. Inhibition of this enzyme can be beneficial in the treatment of various inflammatory and lung diseases, such as chronic obstructive pulmonary disease (COPD) and cystic fibrosis.

Rhodium-Catalyzed C6-Selective C-H Borylation of 2-Pyridones

A pyridine-directed, rhodium-catalyzed C6-selective C-H borylation of 2-pyridones with bis(pinacolato)diboron (pinB-Bpin) has been developed. The reaction proceeds smoothly under relatively mild conditions, and the corresponding C6-borylated 2-pyridones are obtained with perfect site selectivity. Subsequent palladium-catalyzed Suzuki-Miyaura cross-coupling is followed by the removal of the pyridine directing group to form the C6-arylated NH-pyridone in an acceptable overall yield.

Rh(I)-Catalyzed Direct C6?H Arylation of 2-Pyridones with Aryl Carboxylic Acids

A Rh(I)-catalyzed C6-selective C?H arylation of 2-pyridones with inexpensive, readily available, safe and structurally diverse aryl carboxylic acids with the aid of a pyridine directing group is developed. This decarbonylative arylation protocol features an easy-to-handle catalytic system, and is amenable to diversely substituted 2-pyridones and aryl carboxylic acids. It allows access to a wide range of C6-arylated 2-pyridones, including those that are difficult to prepare using conventional C?H arylation processes. The method tolerates various electron-neutral, electron-rich and electron-deficient functional groups, and affords the products in 41–91% yields. (Figure presented.).

Manganese-Promoted Regioselective Direct C3-Phosphinoylation of 2-Pyridones

A highly efficient and regioselective manganese-induced radical oxidative direct C?P bond formation between 2-pyridones and secondary phosphine oxides was developed. The C3-selective phosphinoylation was conveniently achieved through a combination of substoichiometric manganese and persulfate oxidant under mild conditions. Various 3-phosphinoylated pyridone products can be obtained in moderate to high yields. Preliminary mechanistic studies suggest that the reaction is likely to involve a radical pathway induced by catalytically active Mn3+ species.

Vinylogous Blaise Reaction: Conceptually New Synthesis of Pyridin-2-ones

A conceptually new synthesis of pyridine rings by a [C 4 + CN] assembly has been developed by applying a vinylogous version of the classic Blaise reaction. The zinc-mediated reaction of (het)aryl or alkyl nitriles with ethyl-4-bromocrotonate pr

Synthesis of mono- and diaza-'pyridones' via stille coupling of alkoxystannanes

Various alkoxy-substituted heterocyclic stannanes provide access to the corresponding substituted 'pyridone' moieties via Stille cross-coupling. Both pyridyl and a series of diazinyl stannanes are prepared, and options for unmasking (via demethylation or debenzylation) of the pyridone unit are evaluated. Georg Thieme Verlag Stuttgart.
