ls 10 were subjected to H–D exchange, methylation, and allylation. The anions generated from 3 and 10 rapidly isomerized to those having a sulfonyl group in an equatorial position to form both equatorial and axial carbanions, in which a slight difference was found toward the subsequent electrophilic attack. The reaction of the dianion of 10 was little affected by an adjacent oxyanion and its countercation
