1,3-Dibromopropan-2-ol (I) was converted into an acyl derivative (VI) by reaction with an appropriate acyl chloride in the presence of pyridine. The acyl derivative (VI) was subjected to nucleophilic substitution with 3 mol. equiv. tris(decyl)methylammonium carboxylate in refluxing hexane. This led to symmetrical diacid triglycerides in 90–94% yield. Substitution with an equimolar amount of the carboxylate
通过在吡啶存在下与适当的酰氯反应,将1,3-二溴丙烷-2-醇(I)转化为酰基衍生物(VI)。对酰基衍生物(VI)进行3摩尔亲核取代。当量 在回流己烷中的羧酸三(癸基)甲基铵。这导致对称的二酸甘油三酯收率达到90-94%。用等摩尔量的羧酸取代,主要提供1,2-双酰氧基-3-溴丙烷(VII),可以轻松地将其分离并进一步取代,从而得到约不对称的二酸和三酸三甘油酯。产率96%。脂解显示合成的甘油三酸酯为约。纯度为99%。
