Pd(II)-Catalyzed Enantioselective C-H Activation of Cyclopropanes
Systematic ligand development has led to the identification of novel mono-N-protected amino acid ligands for Pd(II)-catalyzed enantioselective C-H activation of cyclopropanes. A diverse range of organoboron reagents can be used as coupling partners, and the reaction proceeds under mild conditions. These results provide a new retro-synthetic disconnection for the construction of enantioenriched cis-substituted cyclopropanecarboxylic acids.
