Disclosed are an optically active 3-aminopyrrolidine (3AP) salt having a high optical purity which is useful as an intermediate in an industrial production method of an optically active 3AP, an efficient method for producing it, and an efficient industrial method for optical resolution of 3AP. Optical resolution of 3AP is efficiently carried out by reacting racemic 3AP with optically active 2-methoxyphenylacetic acid in the presence of a mineral acid such as hydrochloric acid in an aqueous solvent, followed by separation of the resulting diastereomer salt constituted by 1 mole of optically active 3AP and 2 moles of optically active 2-methoxyphenylacetic acid.
本发明公开了一种具有高光学纯度的光学活性 3-氨基吡咯烷(3AP)盐,该盐可用作光学活性 3AP 工业生产方法的中间体,还公开了一种生产该盐的高效方法,以及一种对 3AP 进行光学解析的高效工业方法。外消旋 3AP 与具有光学活性的 2-甲氧基苯乙酸在矿物酸(如盐酸)存在下于水性溶剂中反应,然后分离由 1 摩尔具有光学活性的 3AP 和 2 摩尔具有光学活性的 2-甲氧基苯乙酸构成的非对映异构盐,可有效地进行 3AP 的光学解析。
