摘要:

应用核磁共振技术(1H NMR,13C NMR,DEPT,1H-1H COSY,HSQC,HMBC),确定了苯醚甲环唑的2种非对映异构体的结构,准确归属了它们的 1H、13C信号,为其非对映异构体的结构鉴定提供了重要依据.

Abstract:

The molecular structures of diastereomers of difenoconazole were elucidated by 1D NMR and 2D NMR techniques (1H NMR, 13C NMR, DEPT, 1H-1H COSY, HSQC and HMBC). The 1H and 13C NMR chemical shifts of the diastereomers were assigned.

Key words: NMR,  chemical shift assignment, 2D NMR, difenoconazole, diastereomer
