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.
