Twenty acid chlorides, 4-(mono/di-benzyloxy)-4-ketobutanoyl chlorides (Ia–XXa) were synthesised by the reaction of monoesters of succinic acid with thionyl chloride. The product thus obtained (4-benzyloxy-4-ketobutanoyl chlorides) was treated with diethylcadmium to convert it into the corresponding keto-esters (Ib–XXb), the mono/di-benzyl-γ-ketohexanoates, with a good yield. All the compounds thus prepared were characterised by physical, spectroscopic (UV-VIS, IR, 1H NMR, 13C NMR), and mass measurements techniques.
合成了二十种酸氯化物,4-(单/二苄氧基)-4-酮丁酰氯(Ia-XXa),是通过丁二酸单酯与硫酰氯反应得到的。由此得到的产品(4-苄氧基-4-酮丁酰氯)与二乙基镉反应,转化为相应的酮酯(Ib-XXb),即单/二苄基-γ-己酮酸酯,产率良好。所有制备的化合物都通过物理、光谱(UV-VIS、IR、1H NMR、13C NMR)和质谱技术进行了表征。
