Alkyl-4-tosyl-3-carboxymethyl-1,2,3,4-tetrahydroquinoxalin-2-ones were synthesized by means of a key step that consisted in a condensation reaction between o-phenylenediamine and maleic anhydride, followed by tosylation and final alkylation. The X-ray diffraction of 3- carboxymethyl-4-tosyl-1,2,3,4-tetrahydroquinoxalin-2-one benzyl ester (1e) and 1-benzyl-3- carboxymethyl-4-tosyl-1,2,3,4-tetrahydroquinoxalin-2-one benzyl ester (1f) is reported.

Novel synthesis of 1-alkyl-4-tosyl-3-carboxymethyl-1,2,3,4-tetrahydroquinoxalin-2-ones
