reaction of aldehydes with methyl dichloroacetate, reacted with aromatic compounds in the presence of aluminium chloride to afford α-aryl-β-chloro-α-hydroxyalkanoate 3. The intra-molecular nucleophilic addition of epoxide 1′ gave cyclisation compound 4. The scope and limitation of these reaction were studied for various aldehydes and aromatic compounds. The reaction was also studied in the presence of aluminium
通过醛与二氯乙酸甲酯的Darzens缩合反应获得的环氧化物1,在氯化铝的存在下与芳族化合物反应,得到α-芳基-β-氯-α-羟基链烷酸酯3。环氧化物1 '的分子内亲核加成得到环化化合物4。对于各种醛和芳族化合物,研究了这些反应的范围和局限性。还在负载在氧化铝或硅胶上的氯化铝存在下研究了该反应,该氯化铝被认为是温和的路易斯酸,对环境无害。
