The reaction of citral with anhydrous base leads initially to a cyclohexa-1,3-dienecarbaldehyde. Stronger base and longer reaction times result in deconjugation to a cyclohexa-1,4-diene-carbaldehyde, together with oxidative loss of six carbon atoms to yield 2-methyl-4-(4-methylpent-3-enyl)benzaldehyde. A mixed aldol reaction between citral and 3-methyl-2-butenal (= senecia aldehyde) is described.
柠檬醛与无水碱的反应最初导致环己-1,3-二烯甲醛。较强的碱和较长的反应时间导致与六氟环己-1,4-二烯-甲醛的共轭结合,以及六个碳原子的氧化损失,从而生成2-甲基-4-(4-甲基戊-3-烯基)苯甲醛。描述了柠檬醛和3-甲基-2-丁烯醛(=千里光醛)之间的混合羟醛反应。
