Cu-Catalyzed Synthesis of 2-Silyl-1,3-butadienes from Allenols and Applications to One-Pot Synthesis of Tetrasubstituted Arylsilanes
chemo- and stereoselective method for the synthesis of (E)-2-silyl-1,3-butadienes from a broad range of allenols using mild Si–B reagents is reported in this study. Our protocol required a short reaction time at ambient temperature to produce the desired dienes in high yields. Synthetic applications are highlighted by the one-potsynthesis of tetrasubstituted arylsilanes from allenols as well as the
本研究报道了一种铜催化化学和立体选择性方法,使用温和的 Si-B 试剂从多种联烯醇合成 ( E )-2-甲硅烷基-1,3-丁二烯。我们的方案需要在环境温度下进行短反应时间才能以高产率产生所需的二烯。从联烯醇一锅合成四取代芳基硅烷以及 C-Si 键的进一步功能化突出了合成应用。
