Total synthesis of (-)-dictyostatin, a microtubule-stabilising anticancer macrolide of marine sponge origin

An efficient convergent synthesis of the anticancer marine macrolide (-)-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 insta

Total synthesis of a potent hybrid of the anticancer natural products dictyostatin and discodermolide

A potent dictyostatin-discodermolide hybrid was designed and synthesised; it showed enhanced cell growth inhibitory activity relative to discodermolide in four human cancer cell lines including the Taxol-resistant NCI/ADR-Res cell line. The Royal Society of Chemistry.

Synthesis and biological evaluation of novel analogues of dictyostatin

Novel analogues of the microtubule-stabilising agent dictyostatin were designed using existing SAR information from the structurally related discodermolide, synthesised by a late-stage diversification strategy and evaluated in vitro for growth inhibition

Total Synthesis of Rapamycin

Details of the total synthesis of rapamycin (1) are reported.The synthesis required the preparation of intermediates 4-9 in nonracemic form; key coupling reactions included a chromium-mediated addition of vinyl iodide 8 to aldehyde 7 and an Evans aldol reaction to couple fragments 62 and 9.Intermediates 4 and 6 were joined through an amide bond formation to afford advanced intermediate 71.Swern oxidation of the diol in 71 was followed by a selective removal of the TES groups and a second Swern oxidation.Finally, removal of the remaining silyl protecting groups provided fully deprotected, penultimate intermediate 2 in which all carbons were in their proper oxidation state.Macrocyclization was achived through a tandem inter/intramolecular palladium-mediated Stille coupling reaction between distannylethene 3 and bis(vinyl iodide) 2.This latter process accomplished in one step the installation of the remaining two carbons of the natural product and the completion of its total synthesis. - Keywords: rapamycin, stannylethenes, Stille coupling, vinyl iodides
