General description

Yu Fluorination Ligand is widely employed for the chemoselective functionalization of sp2- and sp3 C-H bonds.

Application

The Yu Fluorination Ligand in tandem with Selectfluor(R) (Aldrich 439479) under palladium catalysis can promote direct fluorination of C(sp3)-H bonds stereoselectively. Yu and coworkers have displayed this on amino acid derivatives with directing group assistance from the Yu-Wasa Auxiliary (Aldrich 791806).

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.
