Ru(II)-catalyzed ring-closing metathesis reactions is described. The substrates were appropriately substituted five-, six- and seven-membered cycloalkanes which were spiroannulated by five-, six- and seven-membered rings, respectively. The relative stereochemistry of selected substituted spiranes has been determined by single crystal X-ray analyses. The X-ray structures formed the basis for NMR correlations
描述了使用Ru(II)催化的闭环复分解反应构建官能化螺环的有效方法。适当地替换了五元,六元和七元的底物环烷烃它们分别由五元,六元和七元环成螺旋状。所选取代的螺环烷的相对立体化学已通过单晶X射线分析确定。X射线结构形成了所制备化合物组中相对立体化学的NMR相关性的基础。氧化反应中的相对速率也可以用于立体化学相关。
