A fascinating Fe-promoted protocol for the synthesis of N-arylsulfonamides has been developed. Starting from commercially available nitroarenes and sulfonyl chlorides, moderate to excellent yields of the corresponding N-arylsulfonamides can be obtained. In particular, Fe dust serves as the sole reductant in the transformation and it can be easily performed on a large scale.

N-Substituted 2-exo-hydroxybornyl-10-sulfonamides, prepared as potential chiral auxiliaries for use in asymmetric Morita-Baylis-Hillman (MBH) reactions, have been treated with acryloyl chloride to afford the corresponding 2-exo-Acrylate esters as MBH subs
Camphorsulfonamide derivatives: A new class of chiral catalysts for the titanium alkoxide-promoted addition of dialkylzinc to aldehydes

The enantioselective addition of dialkylzinc to several aldehydes, using different chiral bidentate ligands (3a-j, 4a-h) [derived from (+)-10-camphorsulfonyl chloride] and titanium alkoxide as catalysts, is studied. The influence of temperature, titanium alkoxide, stoichiometry, additive, aldehyde and ligand structure is also studied.
