Abstract Quenching the enolates of cyclic β-diketones or 2-oxocycloalkanecarboxylates with phenylsulfenyl chloride or methylsulfenyl chloride produces the corresponding x- sulfenylated products. Nucleophilic attack on these x-sulfenylated 1, 3-dicarbonyl compounds produces regiospecific sulfenylated linear dicarboxylic acids, acid esters, diesters or oxo esters suitable for further chemical transformation, this has been ...
