  从芳香醛和丝氨酸合成γ-氧代γ-芳基和γ-芳基α-氨基酸

  摘要：

  γ-氧代α-氨基酸和γ-芳基α-氨基酸是具有非常有趣的生物学特性的化合物，是许多药物分子的活性成分。含氧氨基酸还用作许多非天然氨基酸和氨基醇的合成前体。我们报告了通过芳族二噻烷的偶联非常有效地合成此类化合物，该芳族二噻烷由芳族醛和丝氨酸的碘化物衍生物制备。由此获得的化合物中的二噻烷基团可以水解或还原分别生成 4-氧代-4-芳基或 4-芳基 2-氨基丁醇衍生物，在进一步转化时，它们可以转化为标题化合物。从 L-丝氨酸开始提供具有完全对映纯度的相应 D-氨基酸。报告的方法在经济上可行并补充了现有方法，

• Palladium-Catalyzed Cross-Coupling Reactions in One-Pot Multicatalytic Processes
  作者：Hélène Lebel、Chehla Ladjel、Lise Bréthous

  日期：2007.10.1

  Palladium-catalyzed cross-coupling reactions have been investigated in multicatalytic processes to synthesize disubstituted alkenes and alkanes from carbonyl derivatives. The use of copper-catalyzed methylenation reactions is the key starting reaction to produce terminal alkenes which are not isolated, but submitted to further structure elongation. Not only is the isolation of the alkene intermediate

  已经在多催化过程中研究了钯催化的交叉偶联反应，以从羰基衍生物合成双取代烯烃和烷烃。使用铜催化的亚甲基化反应是关键的起始反应，以产生未分离但需要进一步结构延伸的末端烯烃。不仅不需要分离烯烃中间体，而且铜催化剂在钯催化的交叉偶联反应中是一种有益的助催化剂。因此，使用这种一锅法通常以更高的产率获得所需的产品。我们已使用这些方法合成羟基化 (E)-芪类化合物，它们是已知的化学预防和化学治疗剂、气味取代的茚满和非天然氨基酸，如高苯丙氨酸。
