The reaction with β-trifluoromethyl acrylamide3eand azomethine ylides generated froml-proline and several aldehydes provided the corresponding trifluoromethylated pyrrolizidines with excellent diastereoselectivity (>20/1) in all cases and moderate regioselectivity (up to 1/5.9). A DFT calculation was also examined to reveal the origin of these stereoselectivities.
