Enamine chemistry. Part XIV. Reaction of αβ-unsaturated acid chlorides with tertiary enamino-ketones and -esters
Abstract
4-Acetyl- and 4-benzoyl-3-(substituted amino)cyclohex-2-en-1-ones have been isolated from the reaction of acryloyl chloride with tertiary enamino-ketones. Tertiary enamino-ethyl esters give the corresponding 4-ethoxy-carbonylcyclohexenones. 2′,4′-Dimethyl-6′-morpholinoacetophenone has been obtained from the self-condensation of 4-morpholinopent-3-en-2-one and identified from spectral data.
