Enantioselective Lewis Acid Catalyzed ortho Photocycloaddition of Olefins to Phenanthrene‐9‐carboxaldehydes
Visible‐light irradiation (λ=457 nm) enabled the enantioselective ortho photocycloaddition of olefins to phenanthrene‐9‐carboxaldehydes (15 examples, 46–93 % yield, 82–98 % ee). A chiral oxazaborolidine Lewis acid (20 mol %) was employed as the catalyst. It operates by coordination to the aldehyde i...
