  Internal activation of acrylate-type dienophiles for the Diels-Alder reaction. Stereoselective synthesis of conformationally constrained glutamate analogs

  摘要：

  The [4+2] cycloaddition reaction of the unreactive acrylate-type dienophiles such as 5a and 6a was accomplished by introducing an electronegative or electron-withdrawing group as the ester counterpart. Among them, the pentafluorophenyl (PFP) group was found to be an excellent ester counterpart in view of its rate acceleration and chemical stability under the reaction conditions. The C-13 NMR spectral data of the dienophiles with the PFP group suggested that the conjugated CC-double bond was strongly polarized. The internal activation was found to be effective for the related dienophile or other dienes, in particular, unstable to Lewis acid catalysts. A successful application of this method is demonstrated by the syntheses of conformationally restricted analogs of L-glutamate, 3 and 4. (C) 1998 Elsevier Science Ltd. All rights reserved.

  摘要：

  本文介绍了一种从天然丰富的 L-焦谷氨酸中合成 (+)-batzellaside B 的新方法。关键的合成步骤涉及使用乙酰氧基官能化的烯烃底物的 Sharpless 不对称二羟基化，以将两个手性中心非对映选择性地引入结构中。发现可以从所得产物中转化的杂环半胺醛 4 为对映异构体富集的烯丙基化中间体提供立体定向途径，为该天然产物的全合成提供了更好的前景。

  S N 2' sequences have been employed for the synthesis of β-branched α-amino acids using 1,2-diastereocontrol for forming C―C bonds. An oxazolidine fragment derived from Garner's aldehyde provides the handle for facial discrimination and acts as a masked amino acid functionality. This study encompasses directed and non-directed allylic substitution reactions. The stereocontrol of the oxazolidine appendage

  A new method for the synthesis of chiral beta-branched alpha-amino acids based on a copper-mediated directed allylic substitution reaction with Grignard reagents is reported. This is the first case in which a delta-stereogenic center is controlling the diastereoselectivity of an o-DPPB-directed allylic substitution. Depending on the alkene geometry of the starting material either diastereomer, anti
