β-Substituted acrylamides have low electrophilicity and are yet to be exploited in the enantioselective Rauhut–Currier reaction. By exploiting electron-withdrawing protection of the amide and moderate nucleophilicity N-heterocyclic carbenes, such substrates have been converted to enantioenriched quinolones. The reaction proceeds with complete diastereoselectivity, good yield, and modest enantioselectivity. Derivatizations are reported, as are computational studies, supporting decreased amide bond character with electron-withdrawing protection of the nitrogen.

A general method to generate umpolung of aldimines with cyanide was developed via the addition of cyanide to aldimines followed by a proton transfer from the carbon atom to the nitrogen atom in the resulting cyanide adducts. This novel method was successf
Rhodium(III)-catalyzed in situ oxidizing directing group- assisted c-h bond activation and olefination: A route to 2-vinylanilines

A new and efficient method for the synthesis of 2-vinylanilines from the reaction of arylhydrazine hydrochlorides with alkenes and diethyl ketone via a rhodium-catalyzed C-H activation is described. The oxidant-free olefination reaction involves the in situ generation of an -N-N=CR1R2 moiety as the oxidizing directing group thus providing an easy access to 2-vinylanilines.
