Abstract
Anionic species formed by treatment of vinyl sulfones with hydridoaluminates were trapped intramolecularly by esters to provide six- and seven-membered cyclic ketosulfones, e.g. I (R = Me, H, Ar = p-tolyl) and II, exemplified by the stereoselective construction of trans-hydrindanes and of perhydroazulenes. This led to formal syntheses of confertin (III) and damsinic acid.
