wide range of gem‐bisphosphonate tetraethyl esters as precursors for bisphosphonic acids, which are potent inhibitors of bone resorption, bearing alkyl, aryl, and indole substituents in the β position were prepared through the CuII‐catalyzed 1,4‐conjugate addition of boronic acids and indoles to vinylidenebisphosphonate tetraethyl ester.
宽范围的宝石通过将Cu制备-bisphosphonate四乙基酯作为二膦酸,它们是骨吸收的有效抑制剂,轴承烷基,芳基,且在β位的取代基的吲哚前体II催化的1,4-共轭加成的硼酸和吲哚为亚乙烯基双膦酸酯四乙酯。
