Reaction of dimedone with aldehydes and β-aminovinyl carbonyl compounds
The unsymmetrical condensation of dimedone, an aldehyde, and various β-aminovinyl carbonyl compounds, and also bisacetonitrile, has given 3, 4-disubstituted derivatives of 2, 7, 7-trimethyl-5-oxo-1, 4, 5, 6, 7, 8-hexahydroquinoline (Va-f). Compounds Va, d, f have been oxidized with H2CrO4 to the corresponding 3, 4-disubstituted 2, 7, 7-trimethyl-5-oxo-5, 6, 7, 8-tetrahydroquinolines (VIa-c). The IR spectra of compounds Va-c, f and VIa and the UV spectra of compounds Va, c, f, and VIa, c have been recorded.
