ne (Va) is one of the products when the oxime of methyl o-nitrophenyl-pyruvate is reduced with sodium borohydride and palladium–charcoal. The claim that the same quinolone is one of the products of the catalytic hydrogenation of ethyl o-nitrophenylpyruvate oxime is shown to be erroneous. Reduction of the oximino-, benzylidene, and other derivatives of selected keto-esters with sodium borohydride and
3-氨基-1-羟基喹啉-2(1 H)-一(Va)是硼氢化钠和钯-木炭还原邻硝基苯基丙酮酸甲酯的肟时的产物之一。声称相同的喹诺酮是邻硝基硝基丙酮酸乙酯肟的催化氢化产物之一,这一说法被证明是错误的。描述了用硼氢化钠和钯-木炭还原肟基,亚苄基和所选酮酯的其他衍生物。
