examined establishing an efficient method for the preparation of alkyl(1,3-butadien-2-yl)methanols. Application of this method to chiral acetals prepared from (R,R)-2,4-pentanediol led to chiral alkyl(1,3-butadien-2-yl)methanol derivatives with high optical purity which were alternatively synthesized by the Sharpless kinetic resolution of racemic alkyl(1,3-butadien-2-yl)methanols.
已经研究了Ti(IV)氯化钛介导的1-三甲基甲硅烷基-2,3-丁二烯与各种醛和缩醛的反应,建立了制备烷基(1,3-丁二烯-2-基)甲醇的有效方法。该方法在由(R,R)-2,4-戊二醇制得的手性缩醛中的应用可生成具有高光学纯度的手性烷基(1,3-丁二烯-2-基)甲醇衍生物,可以通过Sharpless动力学拆分合成外消旋的烷基(1,3-丁二烯-2-基)甲醇。
