A new synthetic route using biomass-derived furans as starting materials for the production of bis(5-arylfuran-2yl)methane scaffolds was developed. The decarboxylative crosscoupling of 5-hydroxymethylfuroic acid (HMFA) was studied in detail and showed overall good yields. Acid-catalyzed self-condensation was optimized to achieve excellent yields of the target structures. This study highlights the avoidance of protective groups and the utilization of renewable carbon sources as starting materials.
