The highly stereoselective reduction of chiral α-alkyl β-ketosulfoxides with DIBAL/ZnBr2 is governed by the configuration at the sulfur (1,3-induction) and not by that of the C-α (1,2-induction) as it has been previously reported.This fact considerably in

The reaction of 3-(p-tolylsulfinyl)-2-butanone with trimethylsilyl trifluoromethanesulfonate in the presence of diisopropylethylamine gave 3-(p-tolylthio)-2-(trimethylsilyloxy)-1,3-butadiene (2) quantitatively.The Diels-Alder reactions of 2 and the relate
Phosphorus- and Sulfur-substituted Allenes in Synthesis, III. - β-Keto Sulfoxides from 3-Alkyn-1-ols via Allenic Sulfoxides

Allenic sulfoxides 3, readily available by sigmatropic rearrangement of sulfenic esters 2 of 3-alkyn-1-ols 1, can be transformed to give β-keto sulfoxides 9 by nucleophilic addition of diethylamine and subsequent hydrolysis of the formed enamines.
