Abstract
On treatment with 0,05N HC1 in aqueous ethanol both 1,19‐isopropyliden‐ouabagenin (II) and ouabagenin (III) yield two new dehydration products, namely monoanhydro‐ouabagenin and tetraanhydro‐ouabagenin, in the ratio of 1:10. Mono‐anhydro‐ouabagenin is proven to possess the structure of lα, llα‐oxido‐strophanthidol (V); accordingly the structure VII is assigned to the tetraanhydro derivative. The lα,llα‐epoxide group is a characteristic feature for both being novel for the cardenolide series.This publication has 47 references indexed in Scilit:
