The invention is directed to novel synthetic C-glycolipids that selectively induce a ThI-type immune response characterized by enhanced IL-12 secretion and increased activation of dendritic cells. The compounds of the invention are thereby useful in treating infections, cancers, cell proliferative disorders, and autoimmune diseases, both directly and as adjuvants.

An isothiourea-catalyzed enantioselective Michael addition of aryl ester pronucleophiles to vinyl bis-sulfones via C(1)-ammonium enolate intermediates has been developed. This operationally simple method allows the base-free functionalization of aryl esters to form α-functionalized products containing two contiguous tertiary stereogenic centres in excellent yield and stereoselectivity (all ≥99:1 er)
