O-Acetylsukhodianine

Stephania venosa (Bl.) Spreng. (leaves, Menispermaceae (-)-O-Acetylsukhodianine (29) tuberous roots) (-)-Anonaine (30)... 

It is interesting to note that the occurrence of C-7 oxygenated aporphine alkaloids with the C-6a R configuration is limited to the families Annonaceae, Lauraceae, Magnoliaceae, and Menispermaceae. Aporphine alkaloids oxygenated at both C-4 and C-7 have been found in the Annonaceae, but (-)-stephadiolamine /3-A-oxide (48) is the first known alkaloid hydroxyl-ated at both C-4 and C-7 and having a cis relationship between H-6a and H-7. (-)-O-Acetylsukhodianine is the first known example of a naturally occurring 7-acetoxylated aporphine (30).
