The Darzens reaction of dihaloacetic acid esters with aromatic aldehydes produces either arylhaloglycidic or arylhalopyruvic esters depending on the nature of the substituent in the aromatic ring. Alkyl p-methoxyphenylchloropyruvates undergo spontaneous intermolecular cyclocondensation to form pyranone or furanone derivatives depending on the character of the alkyl fragment.
二卤乙酸酯与芳香醛的 Darzens 反应生成芳基卤代缩水甘油酯或芳基卤代丙酮酸酯,这取决于芳环中取代基的性质。烷基对甲氧基苯基氯丙酮酸酯根据烷基片段的特性发生自发的分子间环缩合反应,形成吡喃酮或呋喃酮衍生物。
