The synthesis of new chloramphenicol base‐derived chiral hydroxyl oxazoline ligands, and their use in the first Zn(OTf)2‐catalyzed enantioselective alkynylation of isatins are described. This transformation features mild reaction conditions, a remarkably broad substrate scope, and excellent functional group tolerance, affording the corresponding tertiary propargylic alcohols in high yields and with...
