An enantioselective total synthesis of (−)‐cladospolide B was described. The key steps in this synthesis include(a) a Sharpless asymmetric dihydroxylation to elaborate syn diol at C‐4 and C‐5 positions; (b) a Mitsunobu esterification to reverse the configuration at C‐11 from ( S ) to ( R ); and (c) a ring‐closing metathesis to access the 12‐membered macrocyclic ring.
