A highly convergent access to the late-stage biosynthetic intermediates projerangolid and jerangolid E is presented, and its utility is demonstrated by the synthesis of novel non-natural jerangolid derivatives. The key steps are fragment couplings by Julia–Kocienski olefination and olefin cross metathesis, as well as a stereoselective tetrahydropyran formation by intramolecular oxa-Michael addition
