Synthesis and cycloaddition reactions of polyfluorinated imines
摘要:
Imines 3-6 containing fluorinated N-substituents were prepared by reactions of fluorinated sulfinylamines 1, 2 with hexafluoroacetone and ethyl trifluoropyruvate; trifluoromethylsulfonylimines 3, 5 exothermically reacted with dienes at -50 degrees C to form cycloaddition products 7, 9 and alpha-aminoalkylation products 8, 10.
