The present invention relates to a process for producing an optically active erythro-3-amino-1,2-epoxy compound represented by the following general formula (3): ##STR1## wherein R1 represents a hydrocarbon residue having 3 to 12 carbon atoms; and R2 represents optionally protected amino, provided that when the carbon atom at the *3-position has an S configuration, then the carbon atom at the *2-position has an S configuration, and when the carbon atom at the *3-position has an R configuration, then the carbon atom at the *2-position has an R configuration.
本发明涉及一种用于生产一种由下述通用式(3)表示的光学活性赤霉素-3-氨基-1,2-环氧化合物的方法:其中,R1代表具有3至12个碳原子的碳氢残基;R2代表可选择地保护的氨基,但当*3-位置的碳原子具有S构型时,*2-位置的碳原子具有S构型,且当*3-位置的碳原子具有R构型时,*2-位置的碳原子具有R构型。
