Application

The Wasa-Yu MPAA Ligand has been reported by Yu and coworkers to promote the enantioselective C-H activation of cyclopropanes. This transformation is carried out through the coupling of organoboron reagents using palladium-mediated catalysis.

The Yu program centers around the discovery of catalytic carbon–carbon and carbon–heteroatom bond forming reactions based on C–H activation. Target transformations are selected to enable 1) the use of simple and abundant starting materials such as aliphatic acids, amines and alcohols, and 2) disconnections that drastically shorten the synthesis of a drug molecule or a major class of biologically active compounds.
