AbstractAn efficient and short total synthesis of (−)‐cleistenolide (1) from D‐mannitol with an overall yield of 23.6% is described. The chiron approach for the synthesis of (−)‐cleistenolide involves a one‐C‐atom Wittig olefination, a selective allylic triethylsilyl protection, and a Grubbs‐catalyzed ring‐closure‐metathesis (RCM) reaction as the key steps.
