Diasteroselective and Enantioselective Ir-Catalyzed Allylic Substitutions of 1-Substituted 1-Fluoro-1-(arenesulfonyl)methylene Derivatives

Diasteroselective and Enantioselective Ir-Catalyzed Allylic Substitutions of 1-Substituted 1-Fluoro-1-(arenesulfonyl)methylene Derivatives
Xiaoming Zhao, Wenyan Dan, Jiteng Chen
diasteroselective and enantioselective Ir-catalyzed allylic substitutions of 1-substituted 1-fluoro-1-(arenesulfonyl)methylene derivatives are presented, which afford the fluorinated allyl products with two chirality centers. The steric demand of 1-substituted 1-fluoro-1-(arenesulfonyl)methylene derivatives and allylic substrates has a great influence on the dr values of these reactions. The transformation of the branched allyl product into the fluorinated 3,4-dihydro-2H-pyrrole 1-oxide was discussed, as well.
