    摘要： Disclosed is a method for producing an optically active 2-hydroxy ester, comprising selectively esterifying one enantiomer of a racemic 2-hydroxy ester in a solvent containing a catalyst such as tetramisole or benzotetramisole, and a carboxylic acid anhydride, or a carboxylic acid anhydride and a carboxylic acid. In particular, in the case where the solvent contains a carboxylic acid anhydride, but does not contain a carboxylic acid, as the carboxylic acid anhydride, a carboxylic acid anhydride containing a tertiary or quaternary carbon atom in the a-position is used. On the other hand, in the case where the solvent contains a carboxylic acid anhydride and a carboxylic acid, as the carboxylic acid, a carboxylic acid containing a tertiary or quaternary carbon atom in the a-position is used.

    摘要： Disclosed is a novel process for production of lasofoxifene, nafoxidine or an analogue thereof, which comprises reduced number of reaction steps, has a high efficiency, and is practically advantageous. For the production of lasofoxifene or an analogue thereof, a compound represented by the formula (4) is used as an intermediate. The compound represented by the formula (4) can be produced using compounds represented by the formulae (1) to (3) as starting compounds by performing the coupling of the three components in one step.
