  A Simple Procedure for the Regioselective Synthesis of Fatty Acid Esters of Maltose, Leucrose, Maltotriose and n-Dodecyl Maltosides

  摘要：

  The enzymatic acylation of several di- and trisaccharides with acyl donors ranging from 8 to 18 carbon atoms was carried out by transesterification with the corresponding vinyl esters. The reaction was performed in 2-methyl-2-butanol/dimethylsulfoxide mixtures using the lipase from Humicola lanuginosa (immobilized on Celite). Maltose, maltotriose and n-dodecyl maltosides were specifically acylated in the primary hydroxyl of the non-reducing-end glucose moiety; the acylation of leucrose occurred preferentially in the primary hydroxyl of the glucose ring.

  the facile enzymatic preparation of a homologous series of 6′-O-acylmaltose esters and an in-depth evaluation of them revealing that their surfactant properties and thermal stabilities are largely determined by the length of the fatty acid chain. In the first such comparison, we show that the foaming and emulsifying effects of certain of these maltose monoesters are superior to those of their sucrose-derived

  源自蔗糖和脂肪酸等可再生资源的乳化剂是大量的商品化学品，目前通过传统的化学合成技术生产，缺乏以选择性和高效方式形成最理想的（蔗糖）单酯的能力。由替代的，结构更简单但仍然丰富的二糖（如麦芽糖）开发新的乳化剂（表面活性剂）可能是解决此问题的方法。在此，我们报告了一系列6'- O同源酶的简便制备-酰基麦芽糖酯及其深入评估表明，它们的表面活性剂性质和热稳定性在很大程度上取决于脂肪酸链的长度。在第一个这样的比较中，我们表明某些麦芽糖单酯的起泡和乳化作用优于蔗糖衍生和商业开发的对应物。这样，麦芽糖酯作为乳化剂具有很大的潜力，例如可用于食品工业。
