  A route to unsaturated spiroketals from phenylthio hex-2-enopyranosides via sequential alkylation, allylic rearrangement and intramolecular glycosidation

  摘要：

  Alkylated phenylthio hex-2-enopyranosides readily undergo 1,3-phenylthio migration, and treatment of the resulting enol ether with N-iodosuccinimide gives an allyl-oxocarbenium ion which can be trapped intramolecularly by a suitably located hydroxy group to yield an unsaturated spiroketal.
