  A Diastereoselective Intramolecular Hydroamination Approach to the Syntheses of (+)-, (±)-, and (−)-Pinidinol

  摘要：

  A diastereoselective, lanthanocene-catalyzed, intramolecular hydroamination reaction was applied to the preparation of 2,6-disubstituted piperidines. Various metal/ligand arrays in the catalysts were examined using a model substrate to allow optimization of the diastereoselectivity. It was determined that the relationship between metal size and ligand bulk plays an integral role in the transformation. The complex Cp*2NdCH(TMS)(2) converted 2-substituted 8-nonen-4-amines to 2,6-disubsituted piperidines with greater than 100:1 selectivity for the formation of the cis isomer. A short synthesis of pinidinol, an alkaloid isolated from various pine and spruce species, was then carried out to exploit this stereoselective reaction.

  Two new routes to the C(1−10) carboxylic acid core of taurospongin A are presented. In the first route, overall asymmetric hydration of a C(2)−C(3) alkene is achieved by Sharpless AD and selective deoxygenation at C(2); in the second route, the C(3) stereogenic center is set by Tietze asymmetric allylation. A short synthesis of the C(1′−25′) fatty acid combines with the product from the first route

  提出了两种通往牛磺pongin A的C（1-10）羧酸核心的新途径。在第一种途径中，通过Sharpless AD和在C（2）处选择性脱氧来实现C（2）-C（3）烯烃的整体不对称水合；在第二种途径中，C（3）立体异构中心是由Tietze不对称烯丙基化设置的。C（1'-25'）脂肪酸的简短合成与第一种路线的产物结合在一起，完成牛磺pongin A的全部合成。
