The anions of sulfonate esters derived from acidic alcohols olefinate carbonyl compounds. The dependence of the yield and stereochemistry of olefination on the sulfonate ester's alkoxy substituent are consistent with a mechanism where apicophilic alkoxy groups promote olefination via 10-S-5 intermediate 3.
