Aiming at production of an optically active 3-amino nitrogen-containing compound which is useful as an intermediate in synthesis of medicines and pesticides, in particular, an optically active 1-protected-3-aminopyrrolidine derivative, from an inexpensive and readily available raw material by a process which is efficient and can be practiced industrially, an optically active 3-amino nitrogen-containing compound is produced by performing a reaction of an optically active 3-substituted nitrogen-containing compound with ammonia, methylamine, ethylamine or dimethylamine in the presence of water. In addition, a 1-protected-3-aminopyrrolidine derivative is produced by performing a reaction of an optically active 1-protected-3-(sulfonyloxy)pyrrolidine derivative with ammonia, methylamine, ethylamine, or dimethylamine in the presence of methanol, ethanol, n-propanol, or isopropanol under a pressure of less than 30 barr.
本发明旨在从一种廉价且易得的原材料出发,通过一种高效且可工业化实践的方法,制备一种光学活性的3-氨基含氮化合物,该化合物在合成药物和杀虫剂中作为中间体特别有用,特别是一种光学活性的1-保护-3-氨基吡咯烷衍生物。该方法包括在水的存在下,将光学活性的3-取代氮含化合物与氨、甲基胺、乙基胺或二甲胺反应,从而制备一种光学活性的3-氨基含氮化合物。此外,通过在甲醇、乙醇、正丙醇或异丙醇的存在下,在小于30巴的压力下,将光学活性的1-保护-3-(磺酰氧基)吡咯烷衍生物与氨、甲基胺、乙基胺或二甲胺反应,从而制备一种1-保护-3-氨基吡咯烷衍生物。
