A Three-Step Route to Functionalized Pyrrole-2,5-Dicarboxylic Acids from Galactaric Acid. [PDF]
ChemSusChemGalactaric acid (GalA) has been used as substrate for a library of N‐substituted pyrrole‐2,5‐dicarboxylic acids (PDCAs). Existing routes to N‐substituted PDCAs require many steps or lack product isolation. We present a simple, scalable three‐step synthesis from GalA via a 2‐pyrone salt, giving isolated PDCA derivatives in high yield without ...
