Strategy for the synthesis of 4-MMDPA. a synthesis of 4-MMDPA (b) 1D 1H NMR spectra showing the aromatic region of the intermediates generated along the pathway of 4-MMDPA synthesis. The full spectra of all intermediates is reported in Additional file 1: Figure S1. The color labeling of atoms highlights the substitution of certain functional groups in every step
