Establish an efficient, mild synthetic method to generate trifluoromethylated pyridinecarbonitrile derivatives using enaminonitriles and vinyl ethers.
Reacted enaminonitriles with β-trifluoroacetylvinyl ethers under mild reaction conditions.
Tracked reaction progression and isolated intermediate species utilizing specific enol ether precursors.
Condensation of enaminonitriles with β-trifluoroacetylvinyl ethers directly produced the desired trifluoromethylated pyridine derivatives.
Isolated intermediate 3 when enol ether 2a was employed, confirming the stepwise pathway of the cyclization process.
