  Asymmetric synthesis of 5-substituted pyrrolidinones via a chiral N-acyliminium equivalent

  摘要：

  5-Substituted pyrrolidinones 5 were synthesized in good yields and with fair to good diastereoselectivities from the chiral non-racemic oxazolopyrrolidinone 4. Various nucleophiles including cuprates, silanes and phosphites were used. The chiral induction is thought to arise from a chelated N-acyliminium species. (C) 2001 Elsevier Science Ltd.

  Diastereoselective bis-alkylation of chiral non-racemic α,β-unsaturated γ-lactams

  摘要：

  A new chiral non-racemic gamma-lactam 1 easily prepared in one step from (R)-(-)-phenylglycinol was bis-alkylated alpha to the carbonyl function in very high to complete diastereoselectivity. The stereochemistry at the so-formed chiral quaternary center was ascertained through an X-ray crystallographic study.

• Asymmetric Routes Towards Polyfunctionalized Pyrrolidines: A Short Diastereoselective Synthesis of Polyhydroxylated Pyrrolidines and an Indolizidine
  作者：Bruno Dudot、Laurent Micouin、Isabelle Baussanne、Jacques Royer

  日期：1999.4

  Various (2S,3S,4R)-2-[(1R)-1-hydroxyalkyl]pyrrolidine-3,4-diols (11) have been prepared in 8 steps and 13-20% overall yields starting from (R)-(-)-phenylglycinol. This concise approach is based on the condensation of a chiral silyloxypyrrole with aldehydes which gave the (R,R)-aldol compounds in good yields and high diastereoselectivities. The cis-hydroxylation followed by reduction and deprotection gave the desired trihydroxylated pyrrolidines. The same strategy has been successively applied to a formal synthesis of 8a-epi-swainsonine.

  从(R)-(-)-苯甘氨醇出发，通过8步反应制备了各种(2S,3S,4R)-2-[(1R)-1-羟基烷基]吡咯烷-3,4-二醇(11)，总收率13-20%。这种简洁的方法是基于手性硅氧基吡咯与醛的缩合，从而得到(R,R)-醛缩化合物，收率高且立体选择性高。顺式羟基化后还原和脱保护得到所需的三羟基吡咯烷。同样的策略已成功应用于8a-表斯温森碱的正式合成。

  日期：1998.3

  3-Alkyl pyrrolidones 9 were synthesized in good yield and high diastereoselectivity by oc-alkylation of the new chiral non-racemic lactam 8 derived from (R)-(-)-phenylglycinol. After debenzylation and introduction of an electron-withdrawing group, 3-methylpyrrolidone 10 is easily hydrolyzed in a basic medium to produce gamma-aminobutyric acid (GABA) analogue 13.
