connected to the carboxyl groups, were synthesized in moderate to good yields from bis(N-acylbenzotriazoles) 6 and amidines 2. In contrast, the corresponding bis(carboxylic acid) chlorides were not well suited for the synthesis of the compounds 7. 2-Aminothiazole gave the bis-amide 8, where the amidine moieties are part of heterocyclic ring systems. Furthermore, the reaction of a bis-amidine 9 with two equivalents
双(Ñ -acylamidines)7,由连接到羧基的间隔物相连,在中度至良好的产率合成了由二(Ñ -acylbenzotriazoles)6个脒2。相反,相应的双(羧酸)氯化物不太适合用于化合物7的合成。2-氨基噻唑得到双酰胺8,其中am部分是杂环系统的一部分。此外,双-脒的反应9与两个当量Ñ -benzoylbenzotriazole(10) ,得到双官能Ñ -acylamidine 11在碳原子上与间隔基连接。对所有物质进行了全面表征,包括九次X射线衍射研究。 酰化-idine-配体-N-酰基苯并三唑-超分子化学
