Diaminomethylenemalononitrile organocatalysts promote the asymmetric chlorination of simple cyclic β-keto esters such as methyl, ethyl, and benzyl esters of 1-oxo-2,3-dihydro-1H-indene-2-carboxylic acid. This affords the corresponding chiral α-chlorinated
Unified strategy for Iodine(III)-Mediated Halogenation and azidation of 1,3-Dicarbonyl compounds

A mild and rapid (diacetoxyiodo)benzene-mediated formal electrophilic a-azidation of 1,3-dicarbonyl compounds using commercially available Bu 4NN3 as the azide source is reported. The reaction conditions employed are based on optimization studies conducted on the analogous halogenations with Et4NX (X = Cl, Br, I).
Sulfoxide-mediated Umpolung of alkali halide salts

A new protocol for the direct two-electron oxidative Umpolung of alkali halide salts is reported. This procedure, relying on the use of a commercially available sulfoxide as the oxidant, allows the electrophilic halogenation of carbonyl compounds as well as halolactonisation reactions to proceed from the corresponding sodium salts, at room temperature and under mild conditions.
