Synthesis of congeners of migrastatin and dorrigocin A from d-xylose

Migrastatin and dorrigocin A analogues have potential as anti-metastatic agents that act by targeting the actin-bundling protein, fascin. Syntheses of close structural analogues of these agents have been achieved. Wittig and Ando olefination reactions with an aldehyde obtained from d-xylose, respectively, gave two trisubstituted alkene intermediates that were then elaborated into either macrolactone or macrolactam analogues of migrastatin or to an acyclic dorrigocin A analogue.
