Fc‐PIP Catalyzed Asymmetric Synthesis of cis‐2,3‐Dihydrobenzofurans

A highly enantioselective intramolecular Michael addition-Lactonization domino reaction of a range of enon acids catalyzed by nuleophilic organocatalyst (Fc-PIP) was developed, furnishing cis-2,3-dihydrobenzofuran derivatives with excellent enantioselecitivities (94%–98% ee) and good diastereoselectivities (up to 99/1).
