A metal- and oxidant-free, practical and efficient method for the synthesis of highly versatile and synthetically useful ortho-trifluoromethanesulfonylated anilines from arylhydroxylamines and trifluoromethanesulfinic chloride was developed. This rapid tr

Privileged 2-amino-2’-hydroxy-1,1’-binaphthyl (NOBIN) frameworks were constructed through a novel domino arylation of naphthylhydroxylamines with diarylhalonium salts and sigmatropic rearrangement in a transition metal-free fashion. This protocol bears broad substrate generality and proceeds under mild reaction conditions, affording diversified NOBINs in high efficiency with absolute regiocontrol during the rearrangement process. Optically active product was accessible by chiral N-heterocyclic carbene-catalyzed kinetic resolution in one pot or diastereoselective [3,3]-rearrangement guided by a removable chiral auxiliary. Remarkably, diarylchloronium and diarylbrominium salts have been employed as arylation reagents for the first time in assembling such representative biaryl frameworks.

Cycloadditions of nitrones with fluoroallene proceed regiospecifically and with a remarkable stereochemical preference for addition syn to the fluorine substituent.The effects of solvent polarity on the rates and stereochemistry of these cycloadditions are reported and discussed.In general these effects are consistent with those reported for other nitrone cycloadditions, and the activation parameters are also similar.
