An efficient convergent synthesis of the anticancer marinemacrolide (−)-dictyostatin is described that proceeds in 4.6% yield over 27 steps. Most of the stereocentres were configured using substrate control, making use of a common building block to install the C12–C14 and C20–C22 stereotriads, with a lactate boron aldol reaction employed to construct a C4–C10 β-ketophosphonate as utilised in the pivotal
