Ethyl (1R,4S,5R,9S,10R,13S)-5,9,13-trimethyl-14-methyl-ene-14-oxotetra-cyclo-[11.2.1.0.0]hexa-decane-5-carboxyl-ate.


ABSTRACT: The title compound, C(22)H(34)O(3), was synthesized from isosteviol. The asymmetric unit contains of two independent mol-ecules with the same absolute configurations. In both the mol-ecules, the three six-membered rings adopt chair conformations, the stereochemistry of the A/B and B/C ring junctions are trans, and the five-membered ring D adopts an envelope conformation.
