Photocatalytic Achmatowicz Rearrangement on Triphenylbenzene–Dimethoxyterephthaldehyde–Covalent Organic Framework-Mo for Converting Biomass-Derived Furfuryl Alcohol to Hydropyranone

The conversion of biomass-based feedstocks into high-value platform compounds remains a fundamental but challenging topic. Studies on such transformations are sparse due to the complex nature of biomass and limited upgrading strategies. Photocatalytic aerobic oxidation is a promising pathway for making pharmaceutical precursors from biomass-derived chemicals. In this study, we demonstrate the transformation of furfuryl alcohol into dihydropyranone acetyl by using a molybdenum-incorporated triphenylbenzene-dimethoxyterephthaldehyde-covalent organic framework
