%X Dehydrations of methyl 3&#946;-hydroxylupan-28-oate (methyl dihydrobetulate) and methyl 3&#946;-hydroxyurs-12-en-28-oate (methyl ursolate) have been carried out by several different procedures and the constitutions of the crystalline products established. The reactions of &#946;-amyrin methanesulphonate have been re-examined but no product corresponding to &#945;-amyradiene-IV (Noller and Hearst 1950) was obtained crystalline.   Reduction of methyl ursolate methanesulphonate with lithium aluminium hydride afforded uvaol.
