Regioselective oxo-amination of alkenes and enol ethers with N-bromosuccinimide-dimethyl sulfoxide combination: A facile synthesis of α-amino-ketones and esters

An unprecedented conversion of alkenes and enol ethers to the corresponding α-imido carbonyl compounds with excellent regioselectivity and yields has been developed. This oxo-amination process employs readily available N-bromosuccinimide (NBS) and secondary amines as N-sources and dimethyl sulfoxide (DMSO) as the oxidant and also leads to the production of amino alcohols in a single step on reduction, thus broadening the scope of this operationally simple reaction. For the first time, the formation of reactive Me2S+-O-Br species generated by the interaction of NBS with DMSO has been proven.

Radical hydroxyalkylation of C-H bond adjacent to nitrogen of tertiary amides, ureas, and amines

Tertiary amides, ureas, and amines undergo direct intermolecular addition to aldehydes under the Et3B/air conditions, thereby providing a unique and simple means for the radical sp3 C-H transformation of nitrogen-containing molecules. Copyright

Neighbour Group Participation with Reductions and Hydride Abstractions

The reduction of N-(2-hydroxyalkyl)lactams with diisobutylaluminium hydride and the hydride ion abstraction of the corresponding amino alcohols give under neighbour group participation the fused oxazolidines.
