Deoxygenative Coupling Between Morita–Baylis–Hillman Acetates and Unprotected Cycloketone Oximes Enabled by Photoredox/Ti Dual Catalysis

A photoredox/Ti dual‐catalyzed deoxygenative coupling reaction between Morita–Baylis–Hillman acetates and unprotected cycloketone oximes has been developed. A broad range of cyano‐containing trisubstituted alkenes have been expediently synthesized in good chemo‐ and stereo‐selectivities under very mild conditions. Mechanistic experiments, scale‐up reaction, and functionalization of complex molecules were conducted, in order to showcase the mechanistic features and robustness of this protocol.
