We report the synthesis of the first optically active silyl esters of phosphorus hewing too centres of chirality : one on silicon and the other on phosphorus. Compounds we obtained of general formula : t-BuPhP(X)YSiαNpPhMe X,Y=0,0(1): S, (2); Se, 0(3); S, 3(4); doublet, 0(5) including 1 and 3 with optical activity located on Si, 2 and 5 with the activity on Si or P and on both these centras, 4 only
我们报道了磷的第一种旋光活性甲硅烷基酯的合成,它们也具有手性中心:一个在硅上,另一个在磷上。我们得到的通式为:t-BuPhP(X)YSiαNpPhMeX,Y = 0,0(1):S,(2); m = 1。Se,0(3);S,3(4);doublet,0(5)包括在Si上具有光学活性的1和3,在Si或P上以及在这两个中枢上具有2的旋光活性的2和5。确定绝对配置。报告了这些模型及其三甲基甲硅烷基类似物的31 P和-29 Si NMR谱。三有机甲硅烷基总是优先通过氧原子与磷键合。令人惊讶地,diastereotopio NMR化学位移排除酯1和4的快速迁移1,3 29Si NMR谱对应于四配位硅原子。
