Abstract
A process for preparing an optically active 2-aminopropanal through oxidative cleavage of the corresponding optically active 3-amino-1,2-butanediol of the following formula (2): ##STR1## wherein R1 is a hydrocarbon group having 3 to 6 carbon atoms; R2 and R3 are each a hydrogen atom, or separately or together represent an N-protecting group; and the configuration at the *1 position is S or R. An optically active 2-aminopropanal of high purity can be obtained in a high yield by the process.
