A practical and efficient one-pot method for synthesis of a novel kind of N-attached 1,2,3-triazole-containing bisphosphonates was developed. Michael addition reaction of sodium azide with ethylidene bisphosphonates and 1,3-dipolar click cycloaddition were reasonably integrated into one-pot reaction in the presence of sonication. Vinylidene bisphosphonate, NaN3, and terminal alkyne were employed as
开发了一种实用且有效的一锅法,用于合成新型的含N的1,2,3-三唑双膦酸酯。在超声处理下,叠氮化钠与亚乙基双膦酸酯的迈克尔加成反应和1,3-偶极点击环加成被合理地整合到一锅反应中。使用亚乙烯基双膦酸酯,NaN 3和末端炔烃作为反应物,使用CuSO 4 ·5H 2 O抗坏血酸钠作为催化剂体系,并使用AcOH / H 2 O(1:1 v / v)作为溶剂体系创造一个酸性环境以获得最佳效率。
