Popis: A regioselective addition of isocyanates to fluoroalkylated α,β-unsaturated imines 1 is described. Fluoroalkyl-substituted triazinane-2,4-diones 4 are obtained by the reaction of phenyl isocyanate with fluorinated imines 1, while fluorinated dihydropyridin-2(1H)-ones 7 are prepared when tosyl isocyanate is used. Tetrahydro-pyridin-2(1H)-one 10 is obtained by catalytic reduction of dihydropyridin-2(1H)-one 7. Computational studies are performed to explain the different behaviors of both isocyanates and the mechanisms of the processes.
