Catechol‐Containing Poly(2‐isopropyl‐2‐oxazoline): Synthesis and Thermoresponsive Behavior in Aqueous Salt Solutions

open access: yesMacromolecular Rapid Communications, EarlyView.
Polymers carrying catechol groups are interesting mussel‐inspired materials for wet adhesion applications or metal ion complexation for wastewater treatment. Here, catechol‐containing poly(2‐isopropyl‐2‐oxazoline)s were synthesized via microwave‐assisted cationic (co)polymerization and examined with regard to their thermoresponsive LCST behavior in ...

A Three-Step Route to Functionalized Pyrrole-2,5-Dicarboxylic Acids from Galactaric Acid. [PDF]

open access: yesChemSusChem
Galactaric 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 ...
