The first asymmetric total synthesis of hyperiones A and B, two norlignans from Hypericum chinense, has been accomplished following a chemoenzymatic approach. Key features of this synthesis include the lipase-catalyzed enantioselective desymmetrization of a prochiral allenic diol and a silver-mediated cycloisomerization of the resulting axially chiral product to furnish the furan core structure. Two alternative pathways, a ruthenium-catalyzed redox isomerization on the one side and a platinum-catalyzed hydrogenation on the other, are described to finally obtain the desired norlignans.
