Abstract An enantioselective and catalytic method for the synthesis of bridgehead quaternary carbon containing bicyclo[3.3.1]nonanes is described. The intramolecular desymmetric arylation of α-disubstituted 1,3-diketones was achieved using a chiral Pd/PHOX complex. A variety of bridged cyclic molecules, common skeleton for polyprenylated acylphloroglucinols, were obtained in up to 84% yield with 86%
