myo-inositol 1,3,4,5-tetraphosphate, Ins(1,3,4,5)P4, continue to be valuable in biological studies. Inositol orthoesters have proved an important class of intermediate to access these compounds. We investigated the ability of steric bulk from a 4-O protecting group to direct DIBAL-H reduction of inositol orthobenzoates to generate the natural Ins(1,4,5)P3 precursor 2,3,6-O-tribenzyl myo-inositol. Introduction
合成的肌醇肌醇1,4,5-三磷酸,项(1,4,5)p 3,和肌醇肌醇1,3,4,5-四磷酸,宏(1,3,4,5)p 4,在生物学研究中继续具有价值。肌醇原酸酯已被证明是获取这些化合物的一类重要中间体。我们研究了空间体积的从4-能力Ò保护基团直接肌醇orthobenzoates的DIBAL-H还原,以产生自然项(1,4,5)p 3前体2,3,6- ö -tribenzyl肌醇肌醇. 赤道 4- C-甲基的引入赋予了完全选择性还原,我们报告了新型 4 - C-甲基的合成-甲基-Ins(1,4,5)P 3和4 - C-甲基-Ins(1,3,4,5)P 4。
