Abstract

Abstract: In an earlier paper2 of this series, we assigned the position of the double bond in anhydrokogagenin, a dehydration product of kogagenin, at C-5 and 6 tentatively. This has now been confirmed to be located at C-4 and 5 from the results of the epoxide formation, manganese dioxide oxidation and the glycol fission reaction. It has been found that the reaction of anhydrokogagenin with acetone containing a small amount of p-toluenesulphonic acid gives an allylic rearrangement product together with the normal acetonide.
