资源简介：
Study of the intramolecular aza-Michael addition reaction from an aminofluorovinylsulfone opens a new route for the synthesis of pyrrolidine derivatives. An unexpected diastereoselective cyclization reaction was observed, leading preferentially to the anti-N-benzylpyrrolidine sulfone. The resulting sulfone was reacted with aldehydes to access β-substituted α-fluoroalkenyl pyrrolidines in one step.
