Synthesis of 5-carboxy-6-methyl-3,4-dihydro-2(1H)-pyridone derivatives and their electrochemical oxidation to 2-pyridones
Smits, Rufus,Turovska, Baiba,Belyakov, Sergey,Plotniece, Aiva,Duburs, Gunars
, p. 84 - 87 (2016/04/04)
A series of variously substituted 5-carboxy-6-methyl-3,4-dihydro-2(1H)-pyridone derivatives were synthesized and their oxidation potentials determined by cyclic voltammetry. The resulting 2-pyridone structure and a tricyclic heterocycle which was formed d

Substituted 3,4-dihydro-2-pyridones have been efficiently prepared by solid-phase synthesis using Wang resin from the immobilised β-ketoester and further Hantzsch-type heterocyclisation.
Novel hexahydrofuro[3,4-b]-2(1H)-pyridones from 4-aryl substituted 5-alkoxycarbonyl-6-methyl-3,4-dihydropyridones
Morales, Alhmed,Ochoa, Estael,Suarez, Margarita,Verdecia, Yamila,Gonzalez, Leandro,Martin, Nazario,Quinteiro, Margarita,Seoane, Carlos,Soto, Jose L.

The title compounds 6 have been prepared in a one-step procedure from the corresponding 4-aryl substituted 5-alkoxycarbonyl-6-methyl-3,4-dihydropyridones 4 in good yields. Quantum chemical calculations reveal a non-planar molecule with a distorted dihydropyridone ring and two favoured conformations. The 13C nmr data and theoretical calculations support a strong push-pull effect on the olefinic moiety.
Synthesis of methyl 4-aryl-6-methyl-4,7-dihydro-1H-pyrazolo-[3,4-b]pyridine-5-carboxylates from methyl 4-aryl-6-methyl-2-oxo-1,2,3,4-tetrahydropyridine-5-carboxylates
