Add time:08/11/2019 Source:sciencedirect.com
Imines 3–6 containing fluorinated N-substituents were prepared by reactions of fluorinated sulfinylamines 1, 2 with hexafluoro-acetone and ethyl trifluoropyruvate; trifluoromethylsulfonylimines 3, 5 exothermically reacted with dienes at –50 °C to form cycloaddition products 7, 9 and α-aminoalkylation products 8, 10.
