A synthesis of 1D- and 1L-myo-inositol 1,3,4,5,-tetraphosphate (1a and 1b resp.) is described. The dibenzylated myo-inositola 9a and 9b, which, by phosphorylation, gave 1a and 1b, respectively, were prepared via two routes. On the one hand, the racemate 3a/3b, obtained from myo-inositol, was resolved by its transformation into the diastereoisomeric carbamates 5a and 5b. Benzylation and deprotecton
1D-和1L-的合成肌肉肌醇1,3,4,5,-tetraphosphate(1A和1B RESP)进行说明。二苯甲基化的肌醇9a和9b通过磷酸化分别通过两种途径制备,分别得到1a和1b。一方面,从肌醇得到的外消旋体3a / 3b通过转化为非对映异构氨基甲酸酯5a和5b而分解。5a和5b的苯甲酰化和脱保护子得到对映异构体9a和9b分别。另一方面,用猪肝酯酶处理二酯18可得到具有高对映体过量的酯21a。21a的苯甲酰化和脱保护得到9b。使用相同的酶水解,然后进行保护-脱保护序列,得到二苄基衍生物9a。
