CONDENSATION OF NITRILES WITH METHYL KETONES AS A METHOD FOR THE SYNTHESIS OF β-AMINOVINYL KETONES

Sosnovskikh, V. Ya.,Ovsyannikov, I. S.

, p. 1801 - 1805 (2007/10/02)

The condensation of nitriles containing aromatic substituents and of trichloroacetonitrile with methyl ketones in the presence of (phenylethylamino)magnesium bromide leads to β-aminovinyl ketones.Acid hydrolysis of the β-aminovinyl ketones gave high yields of the corresponding β-diketones.
