| Abstract: | Anionic species formed by treatment of vinyl sulfones with hydridoaluminates were trapped intramolecularly by esters to provide six- and seven-membered cyclic ketosulfones, exemplified by the stereoselective construction of trans-hydrindanes and of perhydroazulenes. This led to formal syntheses of confertin and damsinic acid. |
