Heating the onion oil component bis(1-propenyl) disulfide gives cis/-and trans-2-mercapto-3,4-dimethyl-2,3-dihydrothiophene which can lose H2S upon further heating giving 3,4-dimethylthiophene. A dithio-Claisen rearrangement is proposed for the key step.detailed

Gold-catalyzed synthesis of 2-deoxy glycosides using S-But-3-ynyl thioglycoside donors

A mild and atom-economic gold(I)-catalyzed glycosylation for stereoselective synthesis of 2-deoxy α- glycosides using bench-stable 2-deoxy S-But-3-ynyl thioglycoside donors has been described. Under optimal conditions, 2- deoxy and 2,6-dideoxy thioglycoside donors were able to react with a variety of primary, secondary, and tertiary alcohol acceptors to afford α-selective glycosides in good to excellent yields.

(Figure Presented) Trapped! The title system (ca. 1 nm diameter; left) catalyzes methanol oxidation with higher turnover rates than clusters on SiO2 supports. Spatial constraints lead to the preferential oxidation of methanol over larger alcohols. Restricted access to active sites also protects encapsulated Ru clusters (right) against inhibition of ethene hydrogenation by organosulfur compounds.

Preparations et heterocyclisations nucleophiles de thiols acetyleniques

Acetylenic thiols HCC(CH2)nSH 1a and HCCCH2Y(CH2)2SH 1b, isolated or prepared in situ from the corresponding thiouronium salts, have been treated with alkali to induce cyclization by intramolecular nucleophilic addition of the thiolate to the triple bond.Starting from the thiol 1a (n = 2) we only isolated thiacyclopent-2-ene 2a, which results from addition to the terminal carbon of the triple bond (yield 45 percent).Higher homologues 1a (n = 3,4), on the other hand, exclusively led to the heterocyclic products 3a resulting from addition to the non-terminal carbon of the triple bond.The best yield was obtained with 1a (n = 3), which led to 2-methylenethiacyclopentane 3a (n = 3) with a 59 percent yield.With the thiol 1a (n = 4), the yield was only 20 percent for 2-methylenethiacyclohexane 3a (n = 4), and with 1a (n = 5) only polymers were formed.When Y = S or N-n-Bu, the substrates 1b behaved like their carbon homologues 1a (n = 3) : yields were in the same range, and the seven-membered heterocycle 2b resulting from attack on the terminal carbon of the triple bond could not be detected.On the other hand, substance 1b (Y = O) mainly led to the seven-membered ring compound 2b.Furthermore, the presence of the heteroatom Y enhanced the possibility of prototropic rearrangement of the triple bond, leading to the new heterocycle 4b in appreciable amounts for Y = O,S.Generally speaking, acetylenic thiolates behave similarly to acetylenic alkoxides, and the same tentative interpretations can be put forward to account for the results obtained.
