1,2-Dihydro-2-oxo-6-(2-methylpropyl)-3-pyridinecarboxylic acid was found to be a hypoglycemic agent but not to have the undesirable mechanism of action possessed by nicotinic acid. A series of 1,2-dihydro-2-oxo-3-pyridinecarboxylic acids with a substituent primarily at the 6-position was prepared by hydrolysis of the corresponding nitriles. The nitriles were prepared by reaction of the sodium enolate
发现1,2-二氢-2-氧代-6-(2-甲基丙基)-3-吡啶甲酸是降血糖剂,但没有烟酸具有的不良作用机理。通过水解相应的腈来制备一系列主要在6-位具有取代基的1,2-二氢-2-氧代-3-吡啶羧酸。通过适当的3-取代的3-氧代丙醛的烯醇钠与氰基乙酰胺的反应来制备腈。由甲酸乙酯和适当的酮与氢化钠或氢化钠合成烯醇钠。以降血糖效力降低的顺序列出的活性1,2-二氢-2-氧代-3-吡啶羧酸具有以下取代基:6-(2,2-二甲基丙基),6-(2,2-二甲基丁基), 6-(1,1-二甲基乙基),6-(2-甲基丙基),6-(1,1-二甲基丙基),1-甲基-6-(2-甲基丙基),6-氢。惰性化合物是具有6-甲基,6-(1-甲基乙基),6-戊基,4-(2,2-二甲基丙基),6-(3-甲基丁基),6-(1,1-二甲基庚基), 6-(2,2-二甲基辛基),6-(1-环丁基甲基)和1-甲基-6-(2,2-二甲基丙基)
