Reaction of ethyl (S)-2-(2-alkyl-1-aziridinyl) acetates with boron trifluoride etherate in a large excess of ethylamine or ammonia gives the corresponding optically active piperazines in good yields. These piperazines retain the configuration of the starting aziridines.
(S)-2-(2-烷基-1-氮丙啶基)乙酸乙酯与乙醚三氟化硼在大量过量的乙胺或氨中反应,以良好的收率得到相应的旋光哌嗪。这些哌嗪保留了起始氮丙啶的构型。
