  使用 NaBH4–NiCl2 通过非对映选择性还原 α-亚苄基-β-苄基-γ-丁内酯简单合成反式-α,β-二苄基-γ-丁内酯木脂素

  摘要：

  反式-α,β-二苄基-γ-丁内酯木脂素是通过使用NaBH4-NiCl2立体选择性还原α-苄叉-β-苄基-γ-丁内酯合成的。发现还原是通过氢化物与 α-亚苄基-β-苄基-γ-丁内酯的共轭加成和所得金属烯醇化物的立体选择性质子化来进行的。立体选择性是由 1,3-烯丙基应变诱导的 α-苄基的苯基部分的构象刚性带来的。

  Dibenzylbutanolide lignans including cordigerines were synthetized and transformed in the corresponding diarylbutane lignans which were submitted to non-phenolic oxidative coupling conditions by using RuO2 or Tl2O3 in trifluoroacetic medium to give deoxyschizandrins. A concurrently aryl-benzyl coupling leads to the formation of the corresponding phenyltetralin of which the structure was confirmed by

  Several butanolide and tetrahydrofuran lignans were synthesized to be comparatively tested as platelet activating factor (PAF) antagonists. In particular, the influence of the tetrahydrofurans ether oxygen as compared with the gamma-lactone system of butanolides was evaluated, showing that the two classes of compounds were practically bioisosters. Molecular modelling and semi-empirical calculation were used to rationalize the collected data.
