The first successful enantioseparation of representative O,O‐diphenyl‐N‐arylthioureidoalkylphosphonates, (±)‐Ptc‐ValP(OPh)2 & (±)‐Ptc‐LeuP(OPh)2 and thiourylenedi(isobutyl phosphonate), Tcm[ValP(OPh)2]2 on analytical and semipreparative scale was achieved by high‐performance liquid chromatography using polysaccharide‐based chiral stationary phases (CPs). Atc‐AAP(OPh)2 was obtained using modified tricomponent
代表性的O,O-二苯基-N-芳硫脲基烷基膦酸酯,(±)-Ptc-Val P(OPh)2和(±)-Ptc-Leu P(OPh)2和硫代脲基二(异丁基膦酸酯)的首次成功对映分离Tcm [ Val P(OPh)2 ] 2的分析和半制备规模是通过使用基于多糖的手性固定相(CP)的高效液相色谱实现的。使用相应醛,N-芳硫脲和亚磷酸三苯酯的改性三组分缩合得到Atc‐AA P(OPh)2,而Tcm [Val P(OPh)2 ] 2通过醛,硫脲和亚磷酸三苯酯的缩合反应。制备的外消旋(±)-Atc-AA P(OPh)2 [(±)-Ptc-Val P(OPh)2,(±)-Ptc-Leu P(OPh)2,(±)-Ptc-Pgly P(OPh)2和(±)-Ntc-Pgly P(OPh)2 ]和外消旋(±)-Tcm [AA P(OPh)2 ] 2 [(±)-Tcm [Nva P(OPh)2 ] 2&(±)-Tcm [Val
