A two-step, one-pot tandem iodocyclization and trifluoromethylation have been developed. A variety of 3-trifluoromethylbenzofurans were prepared in moderate to good yields via the tandem reaction of 2-alkynylanisoles with elemental iodine and (trifluoromethyl)trimethylsilane.
已经开发了两步一锅串联碘环化和三氟甲基化。通过2-炔基茴香醚与元素碘和(三氟甲基)三甲基硅烷的串联反应,以中等至良好的产率制备了各种3-三氟甲基苯并呋喃。
