block with the tetracyclic A/B/C/D ring system, a concise enantioselective totalsynthesis of (−)-cephalotaxine starting from readily available homopiperonyl alcohol has been achieved in nine steps with only two column chromatography purifications. Following the tactical introduction of the Meinwald rearrangement, enantioselective divergent syntheses of (−)-cephalotine B with an additional C3–O–C11
