The sulfone functional group has a strong capacity to direct the asymmetric transfer hydrogenation (ATH) of ketones in the presence of [(arene)Ru(TsDPEN)H] complexes by adopting a position distal to the η6-arene ring. This preference provides a

A N-bromosuccinimide (NBS) mediated decarboxylative sulfonylation of β-keto acids with sodium sulfinates is developed. The transformation exhibits a broad substrate scope and good functional group tolerance. Preliminary mechanistic studies showed that this reaction is likely to proceed through a nucleophilic substitution of β-keto acid with sulfonyl bromide pathway. All synthesized β-keto sulfones were evaluated the inhibitory effect against human carboxylesterase 1 (CES1). This investigation offers an expedient strategy for efficient synthesis of β-keto sulfones that are widely present in biologically active natural products and pharmaceutical agents.

The reaction between 1,1-dithioalkyl phenyl sulphones (11) and ethyl 4-bromobutyrate affords tetrahydro-2-furylidene derivatives (13) together with minor amounts of the cyclopropyl ketones (15).A mixture of the cyclohexanone and dihydropyran derivatives (17) and (18), respectively, is obtained by the reaction of (11) with ethyl 5-bromovalerate.Treatment of the ω-bromo-β-ketosulphone (19) with various basic reagents also gives a mixture of (17) and (18).
