  描述：

  (3S,4R)-N-benzyl-4-(methoxycarbonyl)-2-oxo-1-((S)-1-phenylethyl)pyrrolidin-3-aminium 2,2,2-trifluoroacetate 在 三乙胺 、 N,N-二异丙基乙胺 、 bromo-tris(1-pyrrolidinyl)phosphonium hexafluorophosphate 作用下， 以 二氯甲烷 为溶剂， 反应 13.5h， 生成 (3R,4S)-methyl 4-((3R,4S)-N-benzyl-4-(benzylamino)-5-oxo-1-((S)-1-phenylethyl)pyrrolidine-3-carboxamido)-5-oxo-1-((S)-1-phenylethyl)pyrrolidine-3-carboxylate

  β-Peptoids: synthesis of a novel dimer having a fully extended conformation

  摘要：

  Chiral imines 1a,b, already synthesized in our laboratory, were converted in good yield by reduction into the corresponding N-benzyl-gamma-lactams 2a,b. Desilylation followed by oxidation of the hydroxymethyl functionality gave the N-benzyl-beta-amino acids 5a,b in good yield and high purity. Starting from compound 6a, the corresponding beta-peptoid dimer 8 was prepared, together with its derivatives 9 and 10, these latter displaying conformational restriction about the peptide bond, as evidenced by NMR data.
