to many kinds of molecules containing azide (−N3) functionalities using a “click” chemistry approach. As an example, bisphosphonate trimethyl ester 3a and P,P′-dimethyl ester 2b were attached to triethylene glycol to form triethylene glycol–bisphosphonate conjugates 4 and 5 as model compounds for further studies in, for example, nanoparticle targeting.
新颖(ω-炔-1-羟基-1,1-二基)二膦酸四甲基酯(合成1A - Ç,它们的)P,P ' -二甲基酯(2A - Ç),和两个三甲基酯衍生物(3a中和3b)被报告。使用“点击”化学方法,可以将制备的化合物连接到多种包含叠氮化物(-N 3)官能团的分子上。作为一个例子,二膦酸三甲基酯3A和P,P ' -二甲基酯2b中被附接到三甘醇到形式三乙二醇-二膦酸盐的缀合物图4和5作为模型化合物用于例如纳米粒子靶向的进一步研究。
