A catalytic enantioselective β-O-elimination is reported. The reaction design utilizes the symmetry of meso-ketene acetal substrates and proceeds in the presence of a chiral zirconocene catalyst. Furthermore, a regiodivergent β-O-elimination, the application in diol and amino alcohol synthesis, and a DFT-supported stereochemical analysis are presented.
报道了催化对映选择性 β-O-消除。该反应设计利用内消旋乙烯酮缩醛底物的对称性,并在手性二茂锆催化剂存在下进行。此外,还介绍了区域发散的 β-O-消除、在二醇和氨基醇合成中的应用以及 DFT 支持的立体化学分析。
