While isobutyl vinyl ketone reacts with α-acetyl-α'-methyl succinate to give a normal Michael adduct, the Mannich base or its quaternary derivative as a source of vinylketonc gives the butenolide derivative 8a. Isobutyl cyclohexenoneacetic acid (1b) previously stated to be the reaction product was present only as a by-product. When α-acetyl-α'-methyl succinate is treated with acrylic acid derivatives
异丁基乙烯基酮与α-乙酰基-α'-琥珀酸琥珀酸酯反应生成正常的迈克尔加成物,而曼尼希碱或其四级衍生物(作为乙烯基酮的来源)则生成丁烯内酯衍生物8a。先前说作为反应产物的异丁基环己烯酮乙酸(1b)仅作为副产物存在。当用丙烯酸衍生物处理α-乙酰基-α'-琥珀酸甲酯时,只能得到丁烯内酯8c-8f。
