3-Oxo-18α-olean-28,13β-olide

The title terpene, C(30)H(46)O(3), is a 28,13β-lactone of oleanolic acid prepared with bismuth trifluoromethanesulfonate (OTf), Bi(OTf)(3)·xH(2)O. All rings are trans-fused. The X-ray study shows the inversion of the orientation of 18-H in the lactonization reaction. A quantum chemical ab-initio...
