A method for synthesizing β-sulfanyl ketones via a tandem rearrangement and conjugate addition reaction has been developed. This methodology provides access to a range of β-sulfanyl ketones through the rearrangement of propargyl alcohols to the corresponding enones followed by the conjugate addition of unactivated thiols. The one-pot, tandem transformation is catalyzed by ReOCl3(OPPh3)(S(CH3)2) affording
已经开发了通过串联重排和共轭加成反应合成β-硫烷基酮的方法。通过将炔丙醇重排成相应的烯酮,然后共轭添加未活化的硫醇,该方法学提供了一系列β-硫烷基酮的途径。通过ReOCl 3(OPPh 3)(S(CH 3)2)催化一锅串联转化,可提供高收率的芳基和烷基β-硫烷基酮。
