Herein, an organocatalytic method for photochemical C–O bond cleavage of lignin systems is reported. The use of photochemistry enabled fragmentation of the β-O-4 linkage, the primary linkage in lignin, provides the fragmentation products in good to high yields. The approach was merged with reported oxidation conditions in a one-pot, two-step platform without any intermediary purification, suggesting
本文报道了木质素系统光化学键合C-O键裂解的有机催化方法。光化学的使用使木质素中的主要键β-O-4键断裂,从而以高到高产率提供了断裂产物。该方法与报道的氧化条件合并为一锅两步平台,无需任何中间纯化,表明其高保真度。通过将可见光介导的协议应用于连续流处理,说明了有机催化方法的未来实用性。
