The halogenation of β-ketosulfones such as α-methylsulfonylacetophenone (1) and benzenesulfonylacetone (10) can be effected with sulfuryl chloride or pyridinium bromide perbromide.Regiochemical control can be achieved by control of stoichiometry and/or the reaction conditions.Detailed 1H and 13C nmr, and mass spectra are recorded for a series of halogenated β-ketosulfones, together with structures by X-ray crystallography for 1, 2-chloro-2-methylsulfonyl-1-phenylethanone (2), chloromethyl methyl sulfone (4), and α-chloroacetophenone (21).Results from these studies are used to suggest a reason for the difficulty associated with substitution reactions of α-halosulfones.

The effect of structural change on the biological activity of a series of imidazothiazoles and thiazolobenzimidazoles is described.It was found that compounds with polar substituents at the 2 or 3 position of the ring system are less acutely toxic while maintaining antiinflammatory activity.Other structural changes, such as the incorporation of a gem-dimethyl substituent in the 6 position, increase acute toxicity and eliminate antiinflammatory activity.The compound with the best activity/toxicity ratio contains an alkyl sulfonyl substituent on the thiazole ring.The thiazolobenzimidazole analogues are more potent than the imidazole analogues.
