The glycosylation of 1,2-trans-diequatorial diols derived from tetrabenzoylated and tetrabenzylated D- and L-chiro-inositol with several glycosyl donors has been investigated. An unprecedented dependence of the regioselectivity on the absolute configuration of the acceptor has been found. However this trend is also modulated by the nature of the protecting groups on both the donor and acceptor, with
                                    已经研究了衍生自四苯甲酰化和四苄基化 D-和 L-手性肌醇的 1,2-反式二赤道二醇与几个糖基供体的糖基化。已经发现区域选择性对受体绝对构型的前所未有的依赖性。然而,这种趋势也受到供体和受体上保护基团的性质的调节,苯甲酰化受体提供更高
水平的区域选择性。大多数结果已通过 DFT 计算得到合理化,这表明供体和受体之间的立体电子因素和氢键决定了它们的相对取向并决定了该过程的区域
化学结果。这些研究还强调了与要糖基化的 OH 相邻的酰基在促进糖基化反应中的作用。
