The asymmetric total synthesis of cladospolide D, a natural 12-membered macrolide antibiotic, has been accomplished in 12-steps. Sharpless asymmetric dihydroxylation, Grubb's cross metathesis, and Shiina lactonization have been employed as the key reactions for the installation of the desired stereocenter and the construction of the macrolactone framework.

A short and convergent total synthesis of (+)-cladospolide D is delineated, which involves olefin cross metathesis and furan oxidation to access the γ-oxo-α,β-unsaturated acid and Yamaguchi lactonization to construct the 12-membered ring as key steps.
