dyes, new amphiphilic molecules are needed. In this paper we describe a new class of triblock amphiphiles that we have synthesized by a straightforward convergent approach. These amphiphiles each consist of a nonpolar biphenyl core and a polar shell based on various generations of monoamino polyglycerol dendrons, coupled to the core through amide linkages (1). For the synthesis of these monoamino dendrons
为了提高药物或染料等非极性化合物的水溶性,需要新的两亲分子。在本文中,我们描述了我们通过简单的收敛方法合成的一类新的三嵌段两亲物。这些两亲化合物均由非极性联苯核和基于各代单氨基聚甘油树突的极性壳组成,通过酰胺键与核偶联 (1)。对于这些单氨基树突的合成,我们采用了基于醇基烯丙基化和催化二羟基化的简单迭代两步法。作为起始材料,使用 D,L-丝氨酸/丝氨醇和(在第二个类似途径中)市售的甘油三酯。然后用非极性染料尼罗红在水中研究这些定义的三嵌段两亲物的传输行为。
