Abstract

Biomass-derived commodity chemical 5-hydroxymethyl furfural is an underutilized C6-platform chemical derived from cellulose that is ideal to prepare next-generation value-added products. We have developed an efficient synthetic strategy to access 2,5-diaryl nonsymmetric furans from 5-hydroxymethyl furfural utilizing decarboxylative cross-couplings. A key finding was that the presence of the hydroxymethyl handle enhances the yields of the palladium-catalyzed decarboxylative cross-coupling reaction. The method provides access to a broad-range nonsymmetric 2,5-diaryl furans where each arene can be systematically introduced as required. Additionally, this green synthetic strategy was employed for a formal synthesis of the muscle relaxant Dantrolene in excellent yields.
