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

The ozonolysis of alkenes in methanolic NaOH or NaOMe with CH2Cl2 as cosolvent leads directly to methyl esters.The procedure has been used to prepare various α-, β-, and ω-alkoxy esters, acyloxy esters, and α- and β-N-acyl and N-sulfonyl esters from appropriate unsaturated ethers, esters and amides.Other examples include the formation of dimethyl octanedioate from cyclooctene (75percent yield), dimethyl nonanedioate and methyl nonaoate from methyl oleate (77 and 78percent, respectively), and tetradecanoic acid γ-lactone from 2-methyl-2-hexadecen-6-ol (80percent yield).
