Abstract
A method for producing L-allysine acetal represented by general formula (II), comprising reacting D,L-allysinamide acetal represented by general formula (I) with cells of microorganism or treated cell product having an activity of stereoselectively hydrolyzing L-allysinamide acetal, ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, each independently represent a lower alkyl group, or R.sup.1 and R.sup.2 are combined to form an alkylene group represented by [CH.sub.2 ].sub.n, and n is 2 to 3. D,L-allysinamide acetal represented by general formula (I) is also in the scope of the invention. According to the present invention, L-allysine acetal useful as a raw material for medicine can be produced in a smaller number of steps at low costs.
