  An Efficient Synthesis of Heterocyclic Analogs of 1-Arylnaphthalene Lignans

  摘要：

  The heterocyclic analogs 5a-f, 16, and 20 of 1-arylnaphthalene lignans were synthesized by Diels-Alder reactions of acetoxy aldehydes 11a-f, 14, and 18 with dimethyl acetylenedicarboxylate. A pathway for formation of 5a-f, 16, and 20 through the intermediacy of heteroaromatic isobenzofurans derived from acetoxy aldehydes is discussed.

• Coupling Reactions and Coupling−Alkylations of Thiophenecarbaldehydes Promoted by Samarium Diiodide
  作者：Shyh-Ming Yang、Jim-Min Fang

  DOI：10.1021/jo980851d

  日期：1999.1.1

  The coupling reactions of 2-thiophenecarbaldehyde with aromatic or aliphatic aldehydes were promoted by samarium diiodide in the presence of hexamethylphosphoramide to give C-5 hydroxyalkylation products. The coupling reactions of 3-thiophenecarbaldehyde occurred at C-2, and the subsequent alkylations occurred at the sulfur atom, accompanied by a concurrent opening of the thiophene ring to afford gamma-lactols. Double hydroxyalkylations of 2- and 3-thiophenecarbaldehydes were also carried out under appropriate reaction conditions. Synthetic applications of these thiophenecarbonyl coupling products were demonstrated, for example, by elaboration to furans, butenolides, and thiophene-fused polycyclic compounds.
