A highly convergent, stereoselective total synthesis of diplodialides C and D is described. The protocol involves the use of regioselective ring opening of a chiral epoxide, sequential double alkylation of 1,3-dithiane with a bromide and a chiral epoxide, hydroboration and Yamaguchi macrolactonisation as key steps.

A concise stereoselective total synthesis of diplodialide C
AbstractAn asymmetric totalsynthesis of diplodialide C has been achieved starting from commercially available homoallylic alcohol. Regioselective opening of the chiral epoxide, cross-metathesis reaction, and Yamaguchi macrolactonization were used as the key steps in this synthesis. Graphical Abstract

Stereoselective synthesis of diplodialides-B and C and the formal synthesis of diplodialide-A are reported. A combination of Jacobsen's hydrolytic kinetic resolution and Sharpless epoxidation is used for the creation of two stereogenic centers, while a ring-closing metathesis strategy was used for the construction of the lactone ring.
