Unexpected Formation of 4-[(1-Carbamoyl-3-oxo-1,3-dihydro-2-benzofuran-1-yl)amino]benzoic Acid from 4-[(3-Amino-1-oxo-1<i>H</i>-2-benzopyran-4-yl)amino]benzoic Acid
With the aim of obtaining derivatives belonging to 2′,3′-diphenyl-3<i>H</i>-spiro[[2]benzofuran-1,4′-imidazole]-3,5′(3′<i>H</i>)-dione nucleus, we synthesized 4-[(3-amino-1-oxo-1<i>H</i>-2-benzopyran-4-yl)amino]benzoic acid (a 3,4-diaminoisocoumarine derivative),...
