    • 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.

    • Disclosed is a process for production of an aralkyloxypyrrolidine derivative which is important for the production of a pharmaceutical or the like. A 3-aralkyloxypyrrolidine derivative can be produced in the form of a crystal by a process comprising reacting an N-protected-3-hydroxypyrrolidine with a halogenated aralkyl in the presence of a base and a metal halide and/or a phase transfer catalyst to give an N-protected-3-aralkyloxypyrrolidine, performing the deprotection of the N-protecting group in the product to give a 3-aralkyloxypyrrolidine derivative, and treating the product in a solvent containing a polar solvent. The process can produce a highly pure 3-aralkyloxypyrrolidine derivative in a simple manner, with good efficiency, and in an industrial scale.

    • 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.
