Some methanesulfonateesters of cholane alcohols derived from desoxycholic acid have been prepared and submitted for screening as antitumor agents. Infrared spectra of the dimesylates have distinctive patterns in the 870 to 1000 cm. −1 region, each of which is shown to be virtually superimposable on a composite spectrum of a pair of corresponding mono-mesylates. Antitumor screening test results indicate

lithocholic acid, a number of new cholane derivatives have been prepared consisting of the same or different electron‐donor groups at the 3‐ and 24‐positions. Yields ranged from good to excellent. The donor groups were chosen on the basis of their known ability to coordinate to transition‐metal ions and include pyridyl, 1,3‐dithiolanyl, phenylthioether, and oxime ether groups.
