ABSTRACT:
There are provided a process for preparing an optically active aminopentane derivative that is promising as a psychotropic agent, an antidepressant agent, an antiparkinsonian agent, an anti-Alzheimer's agent, an apoptosis inhibitor, or the like; a novel optically active intermediate oxathiazolidine derivative very useful in the production of the aminopentane derivative; and process for the production thereof.The optically active aminopentane derivatives can be produced in an industrially advantageous manner from a novel optically active oxathiazolidine derivative represented by formula (5):wherein * indicates the position of an asymmetric carbon atom in the R or S configuration, and n is 0 or 1.
