Two strategies towards the synthesis of phosphatidylinositol mannosides (PIMs) were elaborated which permit selective access to the O-1-, O-2-, and the O-6 position of the myo-inositol residue. Starting materials are 1,2:5,6- and 1,2:4,5-di-O-cyclohexylidene-DL-myo-inositol, respectively. In the latter case, the required assignment to the D- or L-series is based on the transformation of one enantiomer
详细说明了两种合成磷脂酰肌醇甘露糖苷(PIM)的策略,它们可以选择性地进入肌醇残基的O-1-,O-2-和O-6位置。起始原料分别是1,2:5,6-和1,2:4,5-二-O-环己叉基-DL-肌醇。在后一种情况下,对D系列或L系列的要求分配是基于一种对映异构体向已知(-)-liriodentritol的转化。两种方法的效率和潜在的多功能性在合成都具有肉豆蔻酰基残基作为磷脂酰部分的PIMs(D)-1a及其假对映体(L)-1b中得到了例证。
