1-Vinyl-2-pyridone, 1-vinyl-4-pyridone, 1-vinyl-2-quinolone, 1-vinyl-4-methyl-2-quinolone, 1-vinyl-4-quinolone, and 1-vinyl-2-methyl-4-quinolone were obtained by the direct vinylation of the corresponding pyridones and quinolones.The sterechemical orientation of the vinyl group in these compounds was established by 1H and 13C NMR spectroscopy.The vinyl derivatives of 2- and 4-pyridones and also 4-quinolone are characterized by a coplanar arrangement of the vinyl group and the heterocycle with the preferred trans orientation in relation to the substituent at the ortho position.In 1-vinyl-2- quinolones and 1-vinyl-2-methyl-4-quinolone the vinyl group and heterocyclic fragment are not coplanar.
