The enantioselective partial hydrolysis of a number of racemic aryl glycidyl ethers in the presence of chiral Co(salen)-catalyst was studied. The enantiomeric composition of the isolated (R)-aryl glycidyl ethers was analyzed by 31P NMR using optically active substituted 2-chloro-1,3,2-dioxaphospholanes. A synthesis of β-adrenoblocking agents (S)-toliprolol and (S)-moprolol based on the simultaneously
研究了在手性 Co(salen) 催化剂存在下,许多外消旋芳基缩水甘油醚的对映选择性部分水解。分离的(R)-芳基缩水甘油醚的对映体组成通过31P NMR使用光学活性取代的2-氯-1,3,2-二氧杂环戊烷进行分析。提出了基于同时获得的 (S)-3-芳氧基丙烷-1,2-二醇合成 β-肾上腺素阻滞剂 (S)-toliprolol 和 (S)-moprolol。
