Reaction of the mesylates of selected glycidols 1b, 5a, 5b and 5c with sodium iodide in acetone has been investigated. The mesylate 1b afforded the iodide 2 and the cyclopropane derivative 3 in a ratio which depended upon the reaction time. Whilst the mesylate 5a provided the iodide 6a as the sole product, the mesylates 5b and 5c gave mixtures of the corresponding unrearranged iodoepoxysilanes 6b and
已经研究了选定的糖苷1b,5a,5b和5c的甲磺酸酯与碘化钠在丙酮中的反应。甲磺酸盐1b以取决于反应时间的比例提供碘化物2和环丙烷衍生物3。甲磺酸盐5a提供碘化物6a作为唯一产物,而甲磺酸盐5b和5c提供相应的未重排的碘代环氧硅烷6b和6c以及环氧化物7b和7c的混合物。
