Asymmetric Synthesis of Trifluoromethylated Allylic Amines Using α,β-Unsaturated N-tert-Butanesulfinimines
摘要:
[GRAPHICS]The trifluoromethide ion generated in situ from TMSCF3 and TBAT (tetrabutylammonium triphenyldifluorosilicate), as well as TMAF (tetramethylammonium fluoride), adds to the alpha,beta -unsaturated hkert-butanesulfinimines exclusively in a 1,2 fashion with high diastereoselectivities, affording the first examples of chiral trifluoromethylated allylic amines.
