Synthesis. 49:2488-2494
Trifluoromethylated piperazines were readily synthesized with excellent regioselectivity in high yields by the sequential reaction of 2-trifluoromethylated N-nosylaziridine (2-CF3-N-Ns-aziridine) with various primary amines, followed by treatment wit

Introduction of the Ns (o-nitrobenzenesulfonyl) group into 2-F3C-aziridine enhanced the useful electrophilic character of the ring, which in turn enabled a base-free ring-opening reaction with indoles under thermal conditions. This method constitutes
