Abstract Reaction of cycloheptanone with potassium persulfate, in ethanol or methanol, gave ethyl or methyl 7-hydroxyheptanoate which, by oxidation with PCC, were converted into ethyl or methyl 7-oxoheptanoate in good yields. Protection of aldehyde group of methyl 7-oxoheptanoate, followed by one-step conversion of carboxylic ester to the acetate gave, after regeneration of aldehyde group, 7-acetoxyheptanal
摘要 环庚酮与过硫酸钾在乙醇或甲醇中反应,得到 7-羟基庚酸乙酯或甲酯,通过 PCC 氧化,以良好的收率转化为 7-氧代庚酸乙酯或甲酯。7-氧代庚酸甲酯的醛基保护,然后羧酸酯一步转化为乙酸酯,醛基再生后得到7-乙酰氧基庚醛。
