The absolute configurations of four hydroxyfatty acids, jalapinolic acid, convolvulinolic acid, ipurolic acid and 3, 11-dihydroxyhexadecanoic acid, obtained by acid hydrolysis of various resin glycosides, have been determined to be 11S, 11S, 3S, 11S, and 3S, 11S, respectively, by Mosher's method. The R-configuration of jalapinolic acid previously defined by Horeau's method was therefore revised to S.
通过酸水解各种树脂糖苷,四种羟基脂肪酸(墨西哥胡椒酸、旋花酸、伊普罗酸和3,11-二羟基十六烷酸)的绝对构型分别被确定为11S、11S、3S、11S和3S、11S,通过莫舍尔法测定。因此,先前由霍罗法定义的墨西哥胡椒酸的R构型被修改为S。
