The ring-opening reaction of 2-trifluoromethyl-N-tosylaziridine with a variety of heteroatom- and carbon-centered nucleophiles was achieved under basic conditions in good to high yield with excellent regioselectivity. These findings enabled an easy access to useful α-trifluoromethyl-N-tosylmethylamine derivatives, such as 1,2-aminoalcohol, 1,2-diamine, 1,2-aminothiol, and distant secondary amine.
2-三氟甲基-N-甲苯磺酰基氮丙啶与各种以杂原子和碳为中心的亲核试剂的开环反应是在碱性条件下以良好至高收率和优异的区域选择性实现的。这些发现使得能够容易地获得有用的α-三氟甲基-N-甲苯磺酰基甲基胺衍生物,例如1,2-氨基醇,1,2-二胺,1,2-氨基硫醇和遥远的仲胺。
