isomers of the monomer of peptide nucleic acid (PNA) were derived from (2S,4R)‐4‐hydroxyproline; they had different stereochemistries at the C2 and C4 positions in the pyrrolidine ring. These different backbone conformations corresponding to four different stereochemistries were realized through a combination of inversions at the C2 and the C4 positions in pyrrolidine ring. The obtained backbone frameworks
肽核酸(PNA)单体的四个异构体衍生自(2 S,4 R)-4-羟基脯氨酸; 它们在吡咯烷环的C 2和C 4位置具有不同的立体化学。通过组合在吡咯烷环中C 2和C 4位置上的转化,实现了与四个不同立体化学相对应的这些不同的主链构象。将获得的主链骨架与N-苯甲酰基胸腺嘧啶反应,得到相应的PNA单体。所得单体的光谱比较证实了其立体化学。J.杂环化学。(2011)。
