There is provided 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 general formula (2):
wherein R1 is a hydrocarbon group having 3 to 6 carbon atoms; R2 and R3 are each a hydrogen atom, or separately or integrally an N-protecting group; and the configuration at the position *1 is S or R.
According to the foregoing process, an optically active 2-aminopropanal of high purity can be obtained in a high yield.
本发明提供了一种通过氧化裂解相应的光学活性 3-氨基-1,2-丁二醇制备光学活性 2-氨基丙醛的工艺,其通式如下(2):
其中 R1 是具有 3 至 6 个碳原子的烃基;R2 和 R3 各为氢原子,或单独或整体为 N-保护基;*1 位上的构型为 S 或 R。
根据上述工艺,可以高产率获得高纯度的光学活性 2-氨基丙醛。
