Reactions of -(-nitroaryl)sarcosine esters with bases give 1-hydroxy-4-methyl-quinoxaline-2,3-diones as the principal products; the corresponding reactions of -(3-nitro-2-pyridyl)sarcosine esters give 1-hydroxy-4-methylpyrido[2,3-]pyrazine-2,3-diones. The significance of these results, in relation to a general mechanism for nitro-group condensations, is discussed.
的反应- (-nitroaryl)肌氨酸酯与碱得到1-羟基-4-甲基-喹喔啉-2,3-二酮作为主产品; -(3-硝基-2-吡啶基)肌氨酸酯的相应反应得到1-羟基-4-甲基吡啶并[2,3- ]吡嗪-2,3-二酮。讨论了这些结果与硝基缩合的一般机理有关的意义。
