Gomez, Elena published the artcile1,4-Dihydropicolinic acid derivatives: novel NADH analogues with an altered connectivity pattern, Synthetic Route of 1690-74-0, the main research area is alkylpyridinium reduction dithionite dihydropyridine NADH analog preparation.
Sodium dithionite reduction of α-substituted N-alkylpyridinium salts derived from picolinic acid derivatives afforded the corresponding 1,4-dihydropyridines with a new substitution pattern, in which the electron-withdrawing group is at the α-position. These compounds promote biomimetic reductions and are hence considered functional NADH analogs.
Tetrahedron Letters published new progress about Reduction. 1690-74-0 belongs to class piperidines, name is Methyl 1-methylpiperidine-2-carboxylate, and the molecular formula is C8H15NO2, Synthetic Route of 1690-74-0.
