The synthesis of phosphatidyl-d-myo-inositol 3,5-bisphosphate [PtdIns(3,5)P2] has been conveniently accomplished via convergent routes starting from both enantiomers, 1,2-O-cyclohexylidene-myo-inositol. The synthetic strategy involves completely regioselective phosphorylation of 3,4-diol and 2,3,6-triol of the suitably protected inositols with the corresponding phosphite in the presence of pyridinium tribromide and 2,6-lutidine, resulting in the formation of 3-O-phosphorylated products, respectively.
从 1,2-O-环己亚甲基肌醇这两种对映体开始,通过趋同的路线可以方便地合成磷脂酰-二-肌醇 3,5-二磷酸[PtdIns(3,5)P2]。合成策略包括在三溴化吡啶和 2,6-Lutidine 的存在下,用相应的亚磷酸酯对经适当保护的肌醇的 3,4 二醇和 2,3,6 三醇进行完全区域选择性磷酸化,分别生成 3-O 磷酸化产物。
