Frontispiece: Highly Enantioselective Organocatalysis with Bidentate Halogen Bond Donors

Strike! A long-standing challenge was finally solved: achieving high enantioselectivity predominantly via halogen bonding (“XB”, see the red stitches) and on unbiased substrates. In their Communication (e202506476), Stefan M. Huber et al. describe the highly enantioselective catalysis of a Mukaiyama aldol reaction by bidentate halogen bond donors.
