TL;DR: A convergent total synthesis of 16-membered macrolactone natural product (−)-A26771B 1 starting from 3,4,6-tri-O-acetyl-D-glucal 7 is reported in this paper.
Abstract: A convergent total synthesis of a 16-membered macrolactone natural product (−)-A26771B 1 starting from 3,4,6-tri-O-acetyl-D-glucal 7 is reported. The Ferrier rearrangement of acetylated glucal 7, cross metathesis between chiral fragments 3 and 4, Yamaguchi macrolactonization and selective oxidation of the allylic alcohol are the key features of the synthesis.

TL;DR: Biological evaluation of one migrastatin and one dorrigocin A sugar derived analogue show that they inhibit proliferation and serum-induced migration of tumour and synovial cells at higher concentrations than evodiamine.
Abstract: The synthesis of a range of analogues of the migrastatin macrolide core has been achieved from tri-O-acetyl-D-glucal in order to facilitate structure-activity studies. Efficient macrolactone formation was achieved in the presence of a reactive olefin, by increasing steric hindrance in the olefin environment. Acyclic analogues of migrastatin, structurally related to dorrigocin A, have also been prepared from D-glucal. The dorrigocin A analogues were prepared using the combination of the cross metathesis of ethyl 6-heptenoate with a glycal derivative and a subsequent allylic rearrangement-alkene isomerisation reaction (Perlin reaction). A synthetic route is thus provided that will enable dorrigocin A analogues to be prepared in parallel to migrastatin analogues in the search for novel anti-cancer and anti-arthritic therapeutics. Biological evaluation of one migrastatin and one dorrigocin A sugar derived analogue show that they inhibit proliferation and serum-induced migration of tumour and synovial cells at higher concentrations than evodiamine. Dorrigocin A analogues displayed similar potency to analogues of the migrastatin core.
