ABSTRACT:
The present invention provides a new method for producing serine derivatives and their optically-activated derivatives in a convenient manner. In the presence of an enzyme, an L-α-amino acid of formula (I):(in the formula (I), R1is a hydrocarbon group)is reacted with an aldehyde of formula (II):(in the formula (II), R2is a hydrocarbon)to produce an L-serine derivative of formula (III)..
