In connection with the studies on biological activities on myrmicacin and related compounds, the synthetic method for 2-hydroxyalkanoic acids and the corresponding 1,2-diols was studied. The addition reaction of tris(methylthio)methyllithium to the aldehydes (propanal–dodecanal) gave the corresponding 1,1,1-tris(methylthio)-2-alkanols 1a–j. Treatment of 1 with mercury(II) chloride–mercury(II) oxide
结合myrmicacin及相关化合物的生物活性研究,研究了2-羟基链烷酸及其相应的1,2-二醇的合成方法。三(甲硫基)甲基锂与醛(丙醛-十二醛)的加成反应得到相应的 1,1,1-三(甲硫基)-2-烷醇 1a-j。在水-丙酮中用氯化汞(II)-氧化汞(II)处理 1 得到 S-2-羟基链烷硫代酸甲酯 2a-j,在甲醇中得到 2-羟基链烷酸甲酯 3c-j。用氢化铝锂还原硫代物 2 得到 1,2-二醇 4c-j,皂化产生相应的 2-羟基链烷酸 5c-j。
