Abstract
The interaction of α-chloro-β,β,β-trifluoroethylisocyanates with ‘push-pull’ enamines having a methyl group at the α-position was investigated. As a result, a set of 4-dialkylamino-6-trifluoromethyl-5,6-dihydro-2-pyridinones was obtained. Structural sensitivity of the reaction was found and discussed.
Key words
‘push-pull’ enamines - isocyanates - trifluoromethyl - dihydropyridines - cyclization
