A method is provided for N-alkylation of acridine compounds by reduction of acridines to corresponding acridans to improve the reactivity of the acridine nitrogen, and subsequent N-alkylation of the acridans in ionic liquid solvents to provide the corresponding acridinium compounds in high yield. This inventive process improves chemical conversion, and does not require the use of highly toxic alkylating agents, such as 1,3-propane sultone.
提供了一种方法,通过将
蒽醌还原为对应的
蒽烷,以改善
蒽醌氮的反应性,并在
离子液体溶剂中进行
蒽烷的N-烷基化,以高收率提供相应的
蒽铵化合物。这种创新的过程提高了
化学转化率,并不需要使用高毒性的烷基化剂,如1,3-
丙磺酸酯。
