A novel and rapid approach for the synthesis of aliphatic polyamide dendrimers, consisting of the 3,4-dialkoxyhydrocinnamamide structure as a repeating unit, has been developed. Aliphatic polyamide dendrons and dendrimers were easily prepared by a convergent approach involving activation of a carboxylic acid at the focal point using (2,3-dihydro-2-thioxo-3-benzoxazolyl)phosphonate (DBOP) as the activating
已经开发了一种新颖且快速的合成脂肪族聚酰胺树枝状大分子的方法,该方法由3,4-二烷氧基氢肉桂酰胺结构作为重复单元。脂肪族聚酰胺树枝状和树枝状聚合物很容易通过收敛方法制备,包括使用(2,3-二氢-2-硫代羰基-3-苯并恶唑基)膦酸酯(DBOP)作为活化剂在焦点处活化羧酸,然后缩合带有未受保护的AB 2构件。由第三代树突和含有两个或三个官能团的核心分子制备哑铃形和星形的第三代树状聚合物。以上所有产物只能通过沉淀纯化,其结构经1证实。H NMR,IR和基质辅助激光解吸电离飞行时间质谱(MALDI–TOF–MS)的光谱学和元素分析。
