Reactions of N-(o-nitroaryl)sarcosine esters with bases give 1-hydroxy-4-methyl-quinoxaline-2,3-diones as the principal products; the corresponding reactions of N-(3-nitro-2-pyridyl)sarcosine esters give 1-hydroxy-4-methylpyridopyrazine-2,3-diones.The significance of these results, in relation to a general mechanism for nitro-group condensations, is discussed.
