2-phenyl- and 2-ethyl-2-trifluoromethylaziridines by Mitsunobu-type cyclisation of the corresponding N-protected amino alcohols, and our results regarding their ring opening with selected nucleophiles. Under basic conditions, N-tosyl aziridines have been regioselectively opened at the less hindered carbon. Under acidic conditions, the regioselectivity of the attack depends on the nature of the substituent
我们在本文中报道了通过相应的N-保护的氨基醇的Mitsunobu-型环化的对映体纯的2-苯基-和2-乙基-2-三氟甲基氮丙啶的合成,以及我们关于它们与选择的亲核试剂的开环的结果。在碱性条件下,N-甲苯磺酰基氮丙啶在较少受阻的碳上被区域选择性地打开。在酸性条件下,进攻的区域选择性取决于C-2上取代基的性质以及氮保护基团。
