Latest Patents
One of his latest patents is titled "Ligand-enabled β-C(sp)-H lactonization for β-C—H functionalizations." This patent describes a method for forming a beta-lactone from a carboxylic acid that has a beta-carbon with a hydrogen atom. The method involves using a palladium(II) catalyst, an N-protected amino acid ligand, and t-butylhydroperoxide in a solvent of hexafluoroisopropanol (HFIP) at approximately 60° C. to produce a beta-lactone. Another notable patent is "Pd(II)-catalyzed enantioselective β-methylene C(sp)—H bond activation." This invention discloses chiral acetyl-protected aminoethyl quinoline (APAQ), pyridine, and imazoline ligands that facilitate the enantioselective arylation or heteroarylation of prochiral β-methylene C—H bonds in aliphatic amides. The systematic tuning of ligand structure
