β¦ Synopsis
The synthesis of the strained epothilone analog containing a ten-membered ring as well as the northern hemisphere of epothilone A is described. This approach, using the ring closing metathesis reaction, is a solution to the lack of stereocontrol observed in the ring closing metathesis reaction utilized in the synthesis of the epothilone backbone by other groups.

A new total synthesis of the novel lactone natural product octalactin A is described. The key step involves the facile construction of the eight-membered lactone core via ring-closing metathesis (RCM). This oxocene was elaborated to give the powerful antitumor agent octalactin A.
