Synthesis of 2,3-Dihydro-4-pyridones and 4-Pyridones by the Cyclization Reaction of Ester-Tethered Enaminones

The Journal of Organic Chemistry, 2020
2,3-Dihydro-4-pyridone skeleton is an important building block in organic synthesis because it features several reaction sites with nucleophilic or electrophilic properties. Herein, we disclose a method for its formation by intramolecular cyclization of ester-tethered enaminones, which can easily be synthesized from readily available materials, such as

Synthesis of Multifunctionalized 2,3-Dihydro-4-pyridones and 4-Pyridones via the Reaction of Carbamoylated Enaminones with Aldehydes

The Journal of Organic Chemistry, 2018
The novel and effective diastereoselective synthesis of multifunctionalized dihydropyridones, including CF3-substituted derivatives, has been developed on the basis of the piperidine-promoted domino reaction of carbamoylated enaminones with aldehydes.

Synthesis of Some N-dialkylaminoalkyl-4-pyridones

Journal of the American Pharmaceutical Association (Scientific ed.), 1950
Attempts to prepare some N-dialkylaminoalkyl-4-alkoxy- and 4-aryloxy-2-pyridones by oxidation of N-dialkylaminoalkyl-4-alkoxy- and 4-aryloxy-pyridinium halides with potassium ferricyanide in alkaline solution resulted instead in the formation of N-dialkylaminoalkyl-4-pyridones as a result of cleavage of the 4-alkoxy or 4-aryloxy group under the ...
