A biosynthetically inspired synthesis of (+)-liphagal has been achieved from (+)-sclareolide in 13 steps (9% overall yield). The key step is a biomimetic ring expansion of a highly stabilized benzylic carbocation, which generates the seven-membered ring and the benzofuran of the natural product in a single cascade reaction.

Enantioenriched compositions of liphagal and its derivatives and precursors include more than 50 mol % of a first enantiomer based on the total amount of a first and a second enantiomer. A method of making an enantioenriched composition includes catalytic enantioselective alkylation, ring expansion, and intramolecular aryne cyclization.
