General description

The catalytic oxidation of methyl 4-aminobenzoate by hydrogen peroxide was studied[1].

Application

Methyl 4-aminobenzoate was used in the syntheses of guanidine alkaloids, (±)-martinelline and (±)-martinellic acid by a protic acid catalyzed hetero Diels-Alder coupling reaction with N-Cbz 2-pyrroline[2].
