Reaction of the methyl ester of ustilic acid A (15,16-dihydroxypalmitic acid) with a methyl Grignard, oxidation of the glycol grouping, bromination, and hydrogenolysis produced 15-methylhexadecanoic acid. A series of 15-keto acids resulted from reaction of the amide of ustilic acid A with the appropriate Grignard reagent followed by oxidation of the glycol grouping. Infrared absorption characteristics of these compounds are described.
使用甲基格氏试剂对乌斯脂酸A(15,16-二羟基棕榈酸)的甲酯进行反应,氧化羟基,溴化和氢解,得到15-甲基十六酸。通过将乌斯脂酸A的酰胺与适当的格氏试剂反应,然后氧化羟基,产生一系列15-酮酸。描述了这些化合物的红外吸收特征。
