A nickel-catalyzed reductive coupling between acid fluorides and vinyl triflates has been described. This method provides an efficient access to various enones and avoids the requirement for acyl or vinyl metallic reagents in the conventional approaches.

The reaction conditions and scope of the photo-Nazarov reaction of aryl vinyl ketones were investigated. In contrast to the conventional acid-catalyzed methods, this photolytic electrocyclization proceeds in the neutral or basic conditions. Irradiating substrates bearing various aromatic rings, acid-sensitive groups, cyclohexenyl, cycloheptenyl, and unsaturated pyran with UV-light (254 nm) smoothly yielded hexahydrofluorenones and related structures. This photo-Nazarov reaction could also be applicable to the substrates carrying β-alkyl groups on the enone, which gave corresponding polycyclic rings containing quaternary centers. These photo-electrocyclized products may prove useful for synthesizing a variety of natural products and their derivatives. Further application of this mild photo-Nazarov reaction in the synthesis of taiwaniaquinol B was achieved.
