Four new polyacetylenic glucosides isolated from the leaf of Jerusalem artichoke (Helianthus tuberosus L.) were characterized as methyl β-D-glucopyranosyl helianthenate C (5), D (6), E (7), and F (8).The absolute stereochemistry of the glucosyloxymethine

Synthetic routes leading to (E)-1,10-di-derivatised dec-2-enes are outlined; in particular the syntheses of (E)-1-benzyloxy-10-methoxyethoxymethoxydec-2-ene and (E)-10-benzyloxy-1-methoxyethoxymethoxydec-2-ene are described.Ring opening reactions between 2-lithio-1,3-dithiane and the oxiranes derived from the above two decenes were studied and the ratio of isomeric dithianyl alcohols produced was shown to be influenced by the nature of the C-1 hydroxyl protecting group.These results are discussed in terms of co-ordinative interactions between the lithiodithiane reagent and the complementary oxygens of the substituted oxiranes.
