  DOI：10.1039/p29830001553

  日期：——

  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％。
