  N-（叔丁基亚磺酰基）卤代胺的不对称转移加氢合成氮化杂环

  摘要：

  已经通过非常有效的方法合成了具有不同环尺寸的高度光学富集，受保护的氮化杂环，该方法包括N-（叔丁基亚磺酰基）卤代胺的不对称转移氢化，然后用碱处理以促进分子内亲核取代过程。ñ-已经获得了具有芳香族，杂芳香族和脂肪族取代基的保护的氮丙啶，吡咯烷，哌啶和氮杂环丙烷，它们的收率非常高，非对映体比例高达> 99：1。游离的杂环可通过简单而温和的脱亚磺酰化方法容易地获得。通过改变亚磺酰基基团的硫原子的绝对构型，可以制备具有相同良好结果的游离杂环的两种对映异构体。

  日期：2000.5

  Chiral, nonracemic 2-substituted pyrrolidines and piperidines were prepared in high ee and moderate to good chemical yields in three steps from (R)-phenylglycinol and γ- or δ-chloroketones. The key step of the synthesis was the stereoselective reductive ring-opening of chiral bicyclic 1,3-oxazolidines prepared by condensation of (R)-phenylglycinol and the corresponding ketones.
