  摘要：

  在碱性条件下，通过硫代邻苯二甲酸酯对醛进行烯化反应，可以高E-立体选择性地合成芪类化合物和苯乙烯基羧酸。该烯化反应具有高度的原子效率，因为在反应过程中仅损失了元素硫。这种烯化反应与逆科尔比-施密特反应相结合，能够简便地合成E-羟基芪类化合物，并最小程度地使用保护基团。这项研究还揭示了两个重要发现：i) 形成4-甲硫基异香豆素和ii) 形成2-芳基茚满酮。

  Oxidative lactonization of 2-carboxystilbene mediated by CuCl2 proceeded regiospecifically to give the five-membered lactone. By utilizing this lactonization as a key reaction, chemical transformation from dihydroisocoumarine into benzylidenephthalide was accomplished, and it was applied to structural elucidation of two new phthalide, hydramacrophyllols A and B.

  The synthesis of stilbenoids and styryl carboxylic acids is accomplished with high E-stereoselectivity by olefination of aldehydes with thiophthalides under basic conditions. The olefination is highly atom-efficient as it only loses elemental sulfur during the reaction. This olefination, in conjunction with retro Kolbe–Schmitt reaction, allows facile synthesis of E-hydroxystilbenoids with minimal employment of protecting groups. This study also discloses two important findings: formation of i) 4-methylsulfanyl isocoumarins and ii) an 2-arylindenone.

  Lactonization reaction of 2-carboxystilbene mediated by copper(II) chloride proceeded regiospecifically to give the five-membered lactone, while the bromolactonizations using N-bromosuccinimide and anodic oxidation were found to furnish the six-membered lactone. Using these regiospecific lactonization reactions as a key step, antiallergic and antimicrobial isocoumarins and the benzylidenephthalides thunberginols A and F and their 3'-deoxyanalogs were synthesized from phyllodulcin and hydrangenol.Two phthalides called hydramacrophyllols A and B were isolated from Hydrangeae Dulcis Folium and their stereostructures were determined on the basis of physicochemical and chemical evidence, which included the syntheses of hydramacrophyllols A and B from hydrangenol by the application of the lactonization method using copper(II)chloride. In addition, hydramacrophyllols A and B were found to exhibit an inhibitory effect on the histamine release from rat peritoneal exudate cells induced by antigen-antibody reaction.
