Modern Photocatalytic Strategies in Natural Product Synthesis

Tandem Vinylogous Aldol and Intramolecular [2 + 2] Cycloaddition toward Benzocyclobutenes by UV Light Photocatalysis

“…Because of their environmentally friendly and unconventional features, photochemical reactions continuously attract intense interest in the design and synthesis of biologically active scaffolds. − A large number of organic reactions have thus been improved in a photochemical modality, and meanwhile, various photopromoted reactions have been successfully applied to the synthesis of bioactive scaffolds and complex natural products. − The privileged benzocyclobutene (BCB) framework shows an emblematic structural characteristic of being widely embodied in abundant bioactive natural products and pharmaceutically relevant compounds (Figure ). − …”
