  Synthesis of Versatile Bifunctional Derivatives of Chiral Diamines Obtained through Anchimerically Assisted Nucleophilic Substitution Reactions on Diastereomeric Phenylprolinols

  摘要：

  Diastereomeric [(S)-1-benzylpyrrolidin-2-yl]-(R)-[(phenyl)methanamine] and [(S)-1-benzylpyrrolidin-2-yl]-(S)-[(phenyl)methanamine], were synthesized by selective internal backside nucleophilic substitution of the corresponding activated phenylprolinols. X-Ray diffraction structures of crystalline acetamide derivatives confirmed the anticipated stereochemistry for a S(N)ib reaction mechanism. In order to apply this reaction to the synthesis of bifunctional analogs, a series of fragments such as a thiourea moiety and sulfonamide functions were introduced for the functionalization of the primary amino group in the substrate, obtaining more stable and potentially useful derivatives.

  通过对映体辅助的亲核取代反应合成非对映体吡咯烷磺酰胺

  摘要：

  在开发方便的合成路线的关键步骤中，Mitsunobu反应用于从（R）-或（S）-[（S）-1-苄基吡咯烷丁-2-基]（）对映选择性制备吡咯烷-磺酰胺配体苯基）甲醇，并使用叔丁基吡咯烷-1--1-基磺酰基氨基甲酸酯作为非常规亲核源。尽管有充分的文献证明，这类非对映体氨基醇暴露于上述亲核试剂通常会导致环扩环形成哌啶，无论是通过经典亲核取代还是Mitsunobu版本，只有吡咯烷衍生物得以保留由于邻近基团的参与（内部背面亲核取代，SNib），在环外立体中心的构型改变。

• Enantioselective Ring Expansion of Prolinols: An Efficient and Short Synthesis of 2-Phenylpiperidin-3-ol Derivatives and 3-Hydroxypipecolic Acids

  日期：2009.8

  A very short route to 2-phenylpiperidin-3-ol derivatives and 3-hydroxypipecolic acids is described. The approach uses two key steps: a one-pot reduction/Grignard addition sequence applied to alkyl proline esters and a ring expansion applied to the corresponding prolinols.

  N-methoxy-N-methylamide derived from (S)-methylpyroglutamate was prepared in good yield and allowed the addition of Grignard reagents. Erythro (2S)-1-benzyl-2-hydroxybenzyl pyrrolidine obtained by this way was converted into (2S,3R)-1-benzyl-3-hydroxy-2-phenylpiperidine and its chloro analog.

• Enantioselective addition of dialkylzinc reagents to N-(diphenylphosphinoyl)imines catalyzed by β-aminoalcohols with the prolinol skeleton
  作者：Raquel Almansa、David Guijarro、Miguel Yus

  DOI：10.1016/j.tetasy.2007.11.006

  日期：2007.11

  Several beta-aminoalcohols with the prolinol framework are shown to be very efficient catalysts for the enantioselective addition of dialkylzinc reagents to N-(diphenylphosphinoyl)imines. The use of 0.5 equiv of the catalyst leads to the expected addition products in good yields and with ee up to 94% in a reaction time of only 4 It at room temperature. This ee is the highest value reported so far using 0.5 equiv of an aminoalcohol as a promoter. High enantioselectivities are obtained in the addition of dialkylzincs to both aromatic and aliphatic imines. The amount of the catalyst can be reduced to 0.25 equiv with a slight decrease in the ee. A very interesting effect of the addition rate and temperature on the enantioselectivity was also observed. (c) 2007 Elsevier Ltd. All rights reserved.
