Angew Chem Int Ed Engl. 1998 Nov 2;37(20):2883-2886. doi: 10.1002/(SICI)1521-3773(19981102)37:20<2883::AID-ANIE2883>3.0.CO;2-Y.

Abstract

Thanks to a productive interaction between reagent and substrate control, 2-alkenylsulfoximides 1 react to provide highly substituted pyrrolidine derivatives 2 enantiomerically pure and with defined absolute configuration at the newly formed stereogenic centers. Tol=tolyl, BOC=tert-butoxycarbonyl.
