  摘要：

  An efficient synthesis of the 2,3-disubstituted piperidines (+)-L-733,060 and (2S,3S)-3-hydroxypipecolic acid (99% ee) in high optical purity from commercially available starting materials is described. The strategy involves a cobalt-catalyzed hydrolytic kinetic resolution of a racemic azido epoxide with two stereocenters and an intramolecular reductive cyclization as key reactions.

• Stereospecific, Flexible and Redox-Economic Asymmetric Synthesis of<i>cis</i>- and<i>trans</i>-3-Hydroxypipecolic Acids and ­Analogs

  trans-3-hydroxy-L-pipecolic acids are synthesized from a common chiral intermediate 7 by a short and flexible route. The stereospecific inversion of C-3 was achieved by the formation of an oxazoline followed by acidic ring cleavage. The overall yields are 27 % and 30 %, respectively, in 12 and 10 linear steps. Several versatile chiral building blocks are also accessible by this diastereodivergent synthesis. Unlike the

  顺式和反式 3-羟基-L-哌啶酸均由常见的手性中间体 7 通过短而灵活的途径合成。C-3 的立体有择反转是通过形成恶唑啉，然后进行酸性环裂解来实现的。在 12 和 10 个线性步骤中，总产率分别为 27% 和 30%。这种非对映发散合成也可以使用几种通用的手性构件。与手性池方法不同，我们的合成策略不受起始材料可用性的限制。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

  A synthetic route to (2S,3S)-3-hydroxypipecolic acid was achieved from readily available nonchiral pool starting material cis-2-butene-1,4-diol and involved Claisen orthoester rearrangement, Sharpless asymmetric dihydroxylation and intramolecular lactamisation of azido lactone as the key steps.
