Abstract Renewable resources based polymers provides a sustainable alternative to petroleum derived polymeric materials. As a part of our series on synthesis of vanillin based renewable polymers, we report the synthesis of poly(hydrovanilloin-furfural) [poly(HVL-Fur)] and poly(hydrovanilloin–5-hydromethylfurfural) [poly(HVL-5-HMF)]. Vanillin was dimerized to a mixtures of meso/DL-hydrovanilloins with 94% meso product by electrochemical reductive coupling in aqueous sodium hydroxide using lead electrodes in quantitative yield. Then sodium hydroxide catalyzed condensation of hydrovanilloin with furfural in water at 80°C for 72 h was used to synthesize poly(HVL-Fur) with Mw = 8600 g mol−1, PDI = 1.28 in 78% yield. Similarly, condensation of hydrovanilloin More >
