  Rongalite® and base-promoted cleavage of disulfides and subsequent Michael addition to α,β-unsaturated ketones/esters: an odorless synthesis of β-sulfido carbonyl compounds

  摘要：

  A highly practical method to access beta-sulfido carbonyl compounds was developed, which could be conducted without any expensive reagent, special apparatus/technique, and no requirement of metal catalysts. beta-Sulfido carbonyl compounds were formed at room temperature, in short time and with high chemoselectivity in good to excellent yields. A plausible mechanism for the role of Rongalite (R), as a promoter for the cleavage of disuffides generating thiolate anions that then undergo facile thia-Michael addition to alpha,beta-unsaturated ketones and esters is proposed.

  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。
