Chiral derivatives of semisquaric acid as new modular ligands for asymmetric catalysis
A family of enantiomerically pure ligands based on the cyclobutenedione structure, and containing either an enantiomerically pure amino alcohol or a diamine as the chiral element, has been synthesized. As first examples of their application, these versatile and modularly constructed ligands have bee...

Summary: | A family of enantiomerically pure ligands based on the cyclobutenedione structure, and containing either an enantiomerically pure amino alcohol or a diamine as the chiral element, has been synthesized. As first examples of their application, these versatile and modularly constructed ligands have been tested in the transfer hydrogenation of acetophenone and in the reduction using borane of this same substrate.
