An oxo-hexaene macrolide antibiotic, dermostatin A has been synthesized. Key features of the synthesis include the application of cyanohydrin acetonide couplings for the synthesis of the polyol portion, and the convergent introduction of the polyene segment by means of a Stille coupling.

first totalsynthesis of the polyene macrolide dermostatin A, confirming our earlier stereochemical assignment. A highly convergent synthesis was developed, featuring the cyanohydrin acetonide method for polyol construction and a Stille approach to polyene introduction. The strategies and tactics developed en route should be of value for the preparation of other members of the polyene macrolide class
