Alkyl-substituted N-(3-oxoalkyl)amides of tosylacetic acid are cyclized under the action of bases with the formation of 3-tosyl-3,6-dihydropyridin-2(1H) -ones. In the presence of a phenyl substituent at position C(1) of the 3-oxoalkyl chain the

, p. 1428 - 1430 (2007/10/03)
2-Pyridones and 1-(4-hydroxy-2-oxo-3-piperidyl)pyridinium chlorides have been obtained by the intramolecular cyclization of N-3-oxoalkylchloroacetamides under the action of tertiary amines.
