Olefinic aldehydes and epoxides with terminal double bonds react with Grignard reagents, and the acetates made from the resulting alcohols undergo double bond cleavage on treatment with RuCl3·xH2O in the presence of NaIO4 to give acetoxy diacids. Hydrolysis with LiOH then affords hydroxy diacids.
带有末端双键的烯烃醛和环氧化物与格氏试剂反应,由所得醇制得的乙酸酯在NaIO 4存在下用RuCl 3 · x H 2 O处理后进行双键裂解,生成乙酰氧基二酸。然后用LiOH水解得到羟基二酸。
