Abstract
Abstract 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-methylpyrido[2,3- b ]pyrazine-2,3-diones. The significance of these results, in relation to a general mechanism for nitro-group condensations, is discussed.
