摘要： 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.

摘要： The objective of the present invention is to produce an optically active 2-arylpiperazine derivative useful as a synthetic intermediate for pharmaceutical products and agricultural chemicals from inexpensive and readily available starting material by an industrially practicable method. The objective can be accomplished by treating an optically active substituted aminodiol derivative produced from an optically active styrene oxide derivative with a sulfonating agent in the presence of a base, and then reacting an amine compound to obtain the 2-arylpiperazine derivative. Especially, an optically active 1-unsubstituted-2-arylpiperazine derivative can be produced by treating an optically active 1-allyl-2-arylpiperazine derivative with water in the presence of a transition metal catalyst for deallylation.

摘要： The present invention provides a process for producing a 3-aralkyloxypyrrolidine derivative which is important for production of pharmaceutical products and the like. In the present invention, a N-protected-3-hydroxypyrrolidine is converted into a N-protected-3-aralkyloxypyrrolidine by allowing an aralkyl halide to act in the presence of a base and at least one of a metal halide and a phase-transfer catalyst followed by deprotecting a N-protecting group to convert it to a 3-aralkyloxypyrrolidine derivative and subsequently treating the derivative in a solvent containing a polar solvent, thereby obtaining the 3-aralkyloxypyrrolidine derivative as a crystal. According to the present invention, a 3-aralkyloxypyrrolidine derivative of high purity can be produced conveniently and efficiently on an industrial scale.
