Catalytic Enantioselective Intramolecular Aza‐Michael Addition to α,β‐Unsaturated Esters
Angewandte Chemie, EarlyView.A general method for accessing enantioenriched saturated N‐heterocycles via a catalytic enantioselective intramolecular aza‐Michael reaction to α,β‐unsaturated esters is described. A superbasic bifunctional iminophosphorane (BIMP) catalyst was key to enabling reactivity of the high pKa sulfonamide pronucleophile, whilst delivering good to excellent ...
