WebChiral Catalysts & Ligands. The quest for novel, efficient chiral catalysts and ligands for enantiopure molecules is an ongoing endeavor in the pharmaceutical, flavors and fragrances, and agrochemical industries. Nearly 85% of new drugs in the market are chiral. This need has led to developments in asymmetric synthesis of chiral ligands and ... WebApr 1, 2024 · Using the JasCp chiral ligand (Figure 1, ligand B), Waldmann and colleagues synthesised five-membered ring atropisomers. These are usually more challenging substrates to make [59] but the synthesis of three types of five-membered rings, axially biaryl heterocycles 24 yielded excellent yields and ee values [60].
