structurally novel antimitotic agent curacin A was prepared in 15 steps and in 2.6% yield for the longest linear sequence. Key steps in our synthesis are the use of a hydrozirconation-transmetalation protocol for the preparation of divinyl alcohol 8, the stereoselective formation of the acyclic triene segment 11 via enol triflate chemistry, and a second hydrozirconation of the conjugatedtriene followed
