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.
从丙烯酰氯与叔烯氨基酮的反应中已分离出4-乙酰基和4-苯甲酰基-3-(取代的氨基)环己-2-烯-1-酮。叔烯氨基乙基酯给出相应的4-乙氧基-羰基环己烯酮。从4-吗啉基opent-3-en-2-one的自缩合反应中获得了2',4'-二甲基-6'-吗啉代乙酰苯,并从光谱数据中鉴定出了该产物。
