fluorine atoms. 13C NMR chemical shifts of mono-, di-, and trifluoroadamantylamines, acids and carbamates reveal long-range fluorine-mediated electronic effects within the adamantane framework, most notably by substrates bearing three bridgehead fluorine atoms. The impact of multiple bridgehead fluorine substitution on structure (X-ray crystallography) and on physicochemical parameters such as acidity
功能化金刚烷被用作药物治疗剂,并且是获得新型桥头氟化金刚胺和酸(包括全氟化 3,5,7-三氟金刚烷-1-羧酸 1 和 3,5,7-三氟金刚烷-1-胺 2)的实用途径描述。高锰酸钾介导的桥头羟基化,然后是 DAST 氟化,用于顺序插入桥头氟原子。单、二和三氟金刚胺、酸和氨基甲酸酯的 13C NMR 化学位移揭示了金刚烷骨架内的长程氟介导的电子效应,最显着的是带有三个桥头氟原子的底物。
