the five-membered ring, and oxidative decarboxylation to generate the key central double bond. The originally suggested stereochemistry for the quaternary center C(5) must be revised, as both C(5) epimers were prepared and a comparison with an authentic sample was made. The absolute configuration of benesudon is 4S,5R,6S.
