simple and new synthetic methods are needed to expand their molecular complexity and also improve their specificity of action towards other targets as anticancer, antibacterial, and antimalarial drugs. Herein, we report a new class of potential antiresorption bisphosphonate drugs that have a pyrrolidine unit with different substituents, obtained through a simple dipolar cycloaddition reaction between
双膦酸盐,特别是带有N-取代基的双膦酸盐,目前是治疗骨质疏松症的最流行药物。但是,它们的化学结构仍然相当简单,需要新的合成方法来扩大其分子复杂性,并提高其对其他靶标(例如抗癌药,抗菌药和抗疟药)的作用特异性。在本文中,我们报告了一种新的潜在的潜在抗吸收性双膦酸酯类药物,该药物具有通过不同的取代基构成的吡咯烷单元,这是通过偶氮甲亚胺基化物和亚乙烯基双膦酸酯衍生物作为前体之间的简单偶极环加成反应获得的。该方法学导致有效制备范围广泛的(1-甲基吡咯烷-3,3-二基)双(膦酸酯)衍生物的4位不同取代基。
