摘要

Abstract An efficient, base-induced rearrangement of 2-[(1, 2-dioxo-2-(methylamino) ethyl) phenylamino] benzoic acid methyl ester (7a) to the isomeric 2-[(1, 2-dioxo-2-(phenylamino) ethyl) methylamino] benzoic acid methyl ester (27a) is described. This novel rearrangement must proceed through a spiro intermediate wherein benzoate is acting as a Michael receptor. When 2-[(1, 2-dioxo-2-(methylamino) ethyl) methylamino] benzoic acid methyl ...
