A general, Bronsted acid-catalyzed hetero-Michael addition of nitrogen, oxygen, and sulfur nucleophiles
Wabnitz, Tobias C.,Spencer, Jonathan B.

(Matrix presented) Strong Bronsted acids such as bis(trifluoromethanesulfon)imide catalyze the hetero-Michael addition of carbamates, alcohols, and thiols to α,β-unsaturated ketones, alkylidene malonates, and acrylimides. Scope, reaction rates, and yields are superior to comparable Lewis acid-catalyzed processes.

The synthesis of enantiomerically pure 1,3-mercaptoalkanol volatile sulfur compounds through a one-pot photo-biocatalytic cascade reaction is described. Two new KRED biocatalysts with opposite enantioselectivity were discovered and proved to be efficient
Potassium phosphate or silica sulfuric acid catalyzed conjugate addition of thiols to α,β-unsaturated ketones at room temperature under solvent-free conditions

, p. 778 - 785 (2007/10/03)
Several γ,δ-unsaturated sulfinyl compounds were prepared and their reactions with p-toluenesulfonic acid were examined. Conformationally rigid γ,δ-unsaturated sulfinyl compounds such as endo-(alkylsulfinyl)norbornene or 1-(alkylsulfinyl)-2-isopropenylbenzene derivatives afforded 1,3-oxathianes through intramolecular Pummerer rearrangement.
