A stereoselectivesynthesis of the C8–C19 segment of cruentarens A and B, cytotoxic natural products, has been accomplished. The key steps involve a stereoselective radical cyclization, stereospecific methylation of a γ, δ-epoxy acrylate, nucleophilic epoxide ring opening and a cis-Wittig olefination.
