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.
研究了δ±-氯-δ²,δ²,δ²-三氟乙基异氰酸酯与在δ-位上具有甲基的 "推拉 "烯胺的相互作用。结果得到了一组 4-二烷基氨基-6-三氟甲基-5,6-二氢-2-吡啶酮。发现并讨论了该反应的结构敏感性。
