A practical procedure for the selective N-alkylation of 4-alkoxy-2-pyridones and its use in a sulfone-mediated synthesis of N-methyl-4-methoxy-2-pyridone

It has been found that selective N-alkylation of 4-alkoxy-2-pyridones can be achieved under anhydrous, mild conditions with tetrabutylammonium iodide and potassium tert-butoxide being employed as the catalyst and the base, respectively. The procedure was applied to the preparation of 4-methoxy-1-methyl-2-pyridone, a valuable building block for heterocycle synthesis.

Lithiation of 4-Methoxy-2-pyridones. Synthetic Entry to Tenellin and Funiculosin, and Related Natural 3,5-Disubstituted 4-Oxy-2-pyridones

Lithiation of 4-methoxy-2-pyridone with butyllithium at -78 deg C occurs at the C-3 position exclusively.Subsequent reactions with MeOD, MeI, CO2, benzaldehyde or (E)-but-2-enal then lead to the corresponding C-3-substituted derivatives. in a one-pot procedure, treatment of 1,2-dihydro-4-methoxy-1-methyl-2-oxopyridine-3-carboxylic acid with ammonia in the presence of a polyphosphate buffer at 80 deg C produced natural ricinine in 58percent overall yield.A convenient three-step synthesis of 5-aryl- and 5-alkyl-substituted 4-methoxy-2-pyridones is described.Lithiation of these substrates, followed by reaction with electrophiles, provided a convenient route to 3,5-disubstituted 4-oxy-2-pyridones, and a synthetic entry to natural products, e. g. tenellin and funiculosin, containing this structural feature.

Syntheses and Ring-opening Reactions of 5-Alkoxy- and 5-Acetoxy-3-oxo-2-azabicyclohex-5-enes

The efficient photochemical synthesis of 5-alkoxy- and 5-acetoxy-3-oxo-2-azabicyclohex-5-enes (2a-e and f, g), and a new rearrangement reaction of the former compounds (2a-e) to 6-alkoxy-2-pyridones (3a-e), are reported.
