Phospha-Michael Addition on α-Fluorinated Acrylates: A Straightforward Access to Polyfunctionalized Fine Chemicals.

α-Fluorinated acrylates could act as Michael acceptors and become a platform toward the synthesis of relevant complex molecules. Very few conjugate additions have been developed in the literature with these specific substrates, and herein, we reported the first phospha-Michael addition (PMA) on α-trifluoromethylacrylates and α-fluoromethylacrylates. The reaction proved to be highly tolerant and gave original products containing contiguous C-P and C-CFY 2 (Y = F or H) bonds in good to excellent yields and diastereoselectivities.
