readily prepared by the one-pot reaction of 2-methylquinolines with CuX (X = I, Br, Cl) and TBHP in CH3CN. A large variety of heterobenzyl iodides, including 2-iodomethylquinolines, 2-iodomethylquinoxalines, 2-iodiomethylbenzooxazole, and 2-iodiomethylbenzothiazole, were efficiently synthesized by one-pot reaction of 2-methylheterocycles with iodine in the presence of CuSO4·5H2O in CH3CN.
针对各种杂苄基卤化物,开发了两种实用且简单的合成方法。通过2-甲基喹啉与CuX(X = I,Br,Cl)和TBHP在CH 3 CN中的一锅反应,可以轻松制备一系列2-卤甲基喹啉。在CuSO 4 ·5H 2 O的存在下,通过2-甲基杂环与碘的一锅反应,有效地合成了包括2-碘甲基喹啉,2-碘甲基喹喔啉,2-碘二甲基苯并恶唑和2-碘甲基苯并噻唑在内的各种杂苄基碘化物。 CH 3 CN。
