anti‐proliferative activity of these compounds in a series of human cancer cell lines, including the taxol‐resistant NCI/ADR‐Res cell line, allowed the proposal of various structure–activity relationships. This led to the identification of a potent macrocyclic discodermolide/dictyostatin hybrid 12 and its C9 methoxy derivative 38, accessible by an efficient total synthesis and with a similar biological profile to

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

employing a diverted total synthesis strategy with late-stage intermediates, 10,11-dihydrodictyostatin ( 5) was prepared and evaluated in vitro for growth inhibition against a range of human cancer cell lines, including the NCI/ADR Taxol-resistant cell line. This novel dictyostatin analogue was found to retain potent antimitotic activity, with a comparable profile to discodermolide and Taxol, functioning
