  • The activation of amines into thiocarbamoyl fluorides provides access to valuable nitrogen-based functionalities. Here, the authors report a mild, photochemical method for in-situ generation of thiocarbonyl difluoride from N-trifluoromethylthiophthalimide using visible light and organic reductants, and apply this strategy to the synthesis of azetidines from strained azabicyclo[1.1.0]butanes.

  • Harnessing the triplet state reactivity of iminium ions has remained a long-standing challenge in photocatalysis. Now it has been shown that structural modification allows direct access to this manifold, overcoming the need for external photosensitizers. This strategy allows the development of organocatalytic enantioselective [2 + 2] photocycloadditions to generate complex cyclobutanes with high stereocontrol.

  • Four-membered rings have become popular motifs in drug discovery, prompting the synthetic organic chemistry community to develop more expedite approaches to access these scaffolds. Here, the authors report a photocatalytic radical strategy for accessing densely functionalized azetidines from azabicyclo[1.1.0]butanes.

  • Controlling diastereodivergent light-driven processes remains synthetically challenging. Here, we disclose how the light source and steric parameters can be used to control the diastereoselectivity of [2 + 2] heterocycloaddition processes, such as in Paternò–Büchi reactions, and provide access to previously inaccessible stereochemical variants.
