A highly efficient and convenient method for the selective titanation of 1,3-butadiynes using Ti(OiPr)4/nBuLi reagent has been developed. The method provided a facilesynthesis of enynes and trans-enynols in a well-stereodefined manner.
开发了一种高效,便捷的方法,用于使用Ti(O i Pr)4 / n BuLi试剂选择性地钛化1,3-丁二炔。该方法以良好的立体确定的方式提供了容易的烯炔和反式烯醇的合成。
