With unique chemical reactivity, α-oxoketene S,S- and N,S-acetals have attracted enormous attention in the past decades, whereas limited reports exist for their synthesis via eco-compatible protocols. Herein, we developed a one-pot protocol for symmetrical and unsymmetrical α-oxoketene S,S-/N,S-acetals through chemoselective alkylation of α-enolic dithioesters using Mitsunobu chemistry at room temperature. The operationally simple and user-friendly mild protocol tolerates a wide range of alcohols and α-enolic dithioesters/β-ketothioamides. Short reaction time, good yields, highly selective C?S functionalization, and E/Z-stereoselectivity are imperative characteristics of this strategy.
