摘要：
Selective depolymerizationof lignin remains a significant challengein biomass conversion. The biosynthesis of lignin involves the polymerizationof monolignol building blocks through oxidative radical coupling reactions.A strategy for lignin degradation leverages photoredox deoxygenativeradical formation to trigger reverse biosynthesis, which cleaves modelcompounds of the beta-O-4 and beta-5-beta-O-4 linkages toproduce monolignols, precursors to flavoring compounds. This mildmethod preserves important oxygen functionality and serves as a platformfor achieving selective lignin depolymerization.
