  A New 1-Alkoxy-2-(chalcogeno)allylic or 1-Alkoxy-2,4-bis(chalcogeno)penta-2,4-dienyl Cation:  Highly-Regioselective Allylating or Penta-2,4-dienylating Electrophiles and Their Reactions

  摘要：

  2-(Chalcogeno)-1-ethoxyallylic cations 4A are easily generated from the reactions of 2-(chalcogeno)-1-ethoxyprop-1-en-3-ols 2a-e or 2-(chalcogeno)prop-2-enal acetals 3a-c and TMSOTf and reacted with various nucleophiles to give the adducts 5a-8a, 5b-11b, and 5c-e regio and stereoselectively. 2,4-Bis(chalcogeno)penta-2,4-dienal acetals 16a,c and the 2,4,6-tris(phenylthio)hepta-2,4,6-trienal acetal 20c also gave the dienones 17a,c and 21c in good yields. Furthermore, the intramolecular cyclization of the alkenyl alcohols 25a,b and the 2,4-dienal 2,4-dinitrophenyl hydrazones 29a-c afforded the tetrahydrofurans 26a,b and 3,5-bis(chalcogeno)pyridines 30a-c, respectively.

  The First Example of the 1-Chalcogene-Substituted Formylolefination of the Ketones and Aldehydes Using 1-Lithio-2-ethoxyvinyl Chalcogenides

  摘要：

  The alpha-chalcogene-substituted formylolefinations of ketones and aldehydes proceeded using 1-lithio-2-ethoxyvinyl chalcogenides/PPSE or TMSOTf produce the alpha-chalcogenoformylolefinated products 4a-1 in high yields. Tandem-formylolefination provided the (2Z,4Z)-2,4-bis(chalcogeno)pent-2,4-dienals 5d,h,i and (2Z,4Z,6Z)-2,4,6-tris(phenylthio)hept-2, derivatives 7d and 8d, respectively.
