    摘要： It is an objective to produce intermediates of optically active beta-3 adrenaline receptor agonists from readily available raw materials in a safe, efficient and industrially advantageous manner. A substituted acetylpyridine derivative represented by the general formula (9) is reduced by enantioselective reduction to produce an optically active hydroxyethylpyridine derivative represented by the general formula (10) (wherein * represents an asymmetric carbon atom), and it is further derivatized to an intermediate of an optically active beta-3 adrenaline receptor agonist, such as an optically active dihydroxyethylpyridine derivative represented by the general formula (14) or an optically active oxirane derivative represented by the general formula (16)

    摘要： The present invention has for its object to provide a method for producing an L-allysine acetal which involves a fewer steps and is efficient. This invention relates to method for producing an L-allysine acetal which comprises; converting a D,L-allysine acetal of the following general formula (1) (wherein R1 and R2 are the same or different, and each of them represents an alkyl group having 1 to 8 carbon atoms, or they combinedly form a ring and represent an alkylene group having 2 to 8 carbon atoms) to a mixture of a 2-oxo-6,6-dialkoxyhexanoic acid of the following general formula (2) (wherein R1 and R2 are as defined above) and an L-allysine acetal of the following general formula (3) (wherein R1 and R2 are as defined above) by reacting in the presence of an enzyme capable of stereoselective oxidative deamination of D-amino acids and; isolating said L-allysine acetal after said converting.
