Ethyl glyoxylate N-tosylhydrazone has been identified as an excellent sulfonyl anion surrogate in the DBU-catalyzed conjugate addition reaction with enones and enals for the synthesis of functionalized sulfones. The reaction proceeds under base-catalyzed conditions and provides a direct access to γ-keto- and γ-hydroxy sulfones in a simple and reliable way through a sulfa-Michael reaction that proceeds with high yield and chemoselectivity.

Carbonate and acyl derivatives of 3-arylsulfonylcyclohexanols and heptanols, upon deprotonation with LHMDS in THF at -78°C, undergo an intramolecular cyclization reaction to give bicyclic lactones or the corresponding acyl transfer products in synthetically useful yields. In contrast, the corresponding cyclopentyl derivatives show different reactivity.
