  非天然芳族α-氨基酸的对映选择性合成。

  摘要：

  我们提出了两种互补方法，用于非天然α-氨基酸与芳香族或杂芳香族侧链的立体选择性合成。一种方法基于蛋氨酸的化学转化，而另一种方法则应用甘氨酸的立体选择性Myers烷基化。所得产物类型在甘氨酸和芳族取代基之间的连接基长度上不同。由于蛋氨酸和伪麻黄碱都可以以两种绝对构型使用，因此可以克量级获得具有C（2）或C（3）接头的R-或S-构型对映纯氨基酸。在每种情况下，合成的关键步骤是不饱和结构单元9和17的硼氢化，然后进行钯催化的Suzuki与芳基卤化物的交叉偶联。在基本的铃木条件下，在某些情况下必须注意立体化学的完整性。报告了我们最初遇到的困难以及最终的“防种族化”程序。为α-氨基酸选择的保护基应与固相肽合成相容。一系列三肽的成功合成证实了这一点。

  A Lewis-acid-catalyzed method for the substrate-directed formation of peptide bonds has been developed, and this powerful approach is utilized for the new "remote" activation of carboxyl groups under solvent-free conditions. The presented method has the following advantages: 1) the high-yielding peptide synthesis uses a tantalum catalyst for any amino acids; 2) the reaction proceeds without any racemization;
