摘要
采用二维核磁共振技术(1 H-1 H COSY,DEPT,HSQC,HMBC,NOESY)和CD光谱,确定了A环开环型芳基萘内酯类木脂素3′,4′-O,O-demethylene-4-O-demethylpodophyllotoxin(1)的结构.首次对化合物1的13C NMR数据进行了全归属.
The 13 C and 1H NMR chemical shifts of a ring A-seco aryltetralin lignan, 3＇,4＇-O,O- demethylene-4-O-demethylpodophyUotoxin, were assigned based on 1D and 2D NMR data, in- cluding 1H-1H COSY, DEPT, HMBC, and HSQC. Stereochemistry was established based on 1H coupling constants （J values）, NOESY results and circular dichroism （CD） results. The 13C NMR signals of the compound was completely assigned for the first time.
