Pavlyuchenko, A. I.,Smirnova, N. I.,Kovshev, E. I.,Titov, V. V.
, p. 957 - 960 (2007/10/02)
The synthesis of 5-alkyl-2-(4-cyanophenyl)pyridines was realized by the keto vinylation of N-4-alkenylpiperidines with 4-bromophenyl β-chlorovinyl ketone followed by cyclization of the obtained 4-piperidino-3-alkyl-1-p-bromobenzoyl-1,3-butadienes to 5-alk
