bases, participate in Michael addition reactions with a variety of conjugated olefins. For singly-activated olefins the conjugate anion reacts intramolecularly with the lactone group to produce 4-hydroxytetralones in moderate to good yield. Dehydration of these hydroxytetralones, by brief treatment with acid, produces the corresponding α-naphthol. Substituted phthalides react similarly making the method
通过受阻碱的处理,从邻苯二甲酸酯的3位衍生而来的锂盐会与多种共轭烯烃一起参与迈克尔的加成反应。对于单活化的烯烃,共轭阴离子与内酯基团在分子内反应,以中等至良好的产率产生4-羟基四氢萘酮。通过用酸进行短暂处理,将这些羟基四氢萘酮脱水,生成相应的α-萘酚。取代的邻苯二甲酸酯的反应相似,从而使该方法成为生产取代的α-萘酚的通用方法。
