  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.

• Synthesis of β-sulfanyl ketones via a tandem rearrangement-conjugate addition reaction catalyzed by a Re(V)-oxo complex

  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。

  found to be an efficient bifunctional catalyst for the 1,4-addition of thiols to α,β-unsaturated ketones. The addition of thiophenol derivatives and alkyl thiols proceeds under mild reaction conditions without pre-activation of the thiol or exogenous base. Reactions of aryl, alkyl, and cyclic enones produce the corresponding β-sulfanyl ketones in good to excellent yield.

  已经发现，ReOCl 3（OPPh 3）（S（CH 3）2）是一种高效的双官能催化剂，可将硫醇1,4-加成到α，β-不饱和酮上。硫酚衍生物和烷基硫醇的添加在温和的反应条件下进行而无需硫醇或外源碱的预活化。芳基，烷基和环状烯酮的反应以良好或优异的产率产生相应的β-硫烷基酮。

  A benign and inexpensive salt, sodium acetate, efficiently catalyzes 1,4-addition of thiols to a variety of conjugated alkenes such as α,β-unsaturated ketones, aldehydes, carboxylic esters, nitriles, nitro compounds, and chalcones in aqueous THF. The reactions are clean, fast, and high yielding.
