A Pd(II)-catalyzed enantioselective C–H alkynylation of 2-(arylsulfinyl)pyridines via kinetic resolution using cheap and commercially available l-pGlu-OH as a chiral ligand is reported. A wide range of 2-(arylsulfinyl)pyridines were compatible with this protocol, giving the alkynylation products and recovered sulfoxides in high yields with high enantioselectivities (up to 99% ee). Furthermore, the
Provided are cyclosporin A analogues that are NTCP inhibitors and useful for treating HBV and/or HDV infection (s), hepatoprotection and amelioration of hypercholesterolemia, diabetes and inhibiting cancer.
