described. The synthetic sequence notably features a Bartlett–Smith halocyclization to give a chiral epoxide, followed by its regioselective ring-opening reaction, Still–Gennari olefination, Corey–Bakshi–Shibata (CBS) ynone reduction, and olefin cross-metathesis. The total syntheses of the proposed structures of the antimalarial lactone cryptorigidifoliol E are described. The synthetic sequence notably
