Highly Enantioselective Organocatalysis with Bidentate Halogen Bond Donors. [PDF]
Angew Chem Int Ed EnglIn a model Mukaiyama aldol reaction with unbiased substrates, high enantioselectivity was achieved with a modifiable bidentate iodine(I)‐based halogen bonding organocatalyst. The crucial role of halogen bonding was confirmed by the low performance of the corresponding hydrogen bond donor and via DFT calculations.
