Catalytic hydrogenation of the oxime, semicarbazone, and phenylhydrazone of 2-nitrophenylpyruvic acid yields indole-2-carboxylic acid and 1-hydroxylindole-2-carboxylic acid. Similar reduction of the oxime of ethyl 2-nitrophenylpyruvate yields a mixture of ethyl indole-2-carboxylate and 3-amino-1-hydroxy-1H-quinolin-2-one.
2-硝基苯基丙酮酸的肟,半脲和苯基hydr的催化加氢产生吲哚-2-羧酸和1-羟基吲哚-2-羧酸。类似地还原2-硝基苯基丙酮酸乙酯的肟,得到吲哚-2-羧酸乙酯和3-氨基-1-羟基-1H-喹啉-2-酮的混合物。
