α-Oxo-Ketenimines from Isocyanides and α-Haloketones: Synthesis and Divergent Reactivity

Jieping Zhu, Qian Wang, Mathias Mamboury

The palladium-catalyzed reaction of a-haloketones with isocyanides afforded -oxo-ketenimines through alpha-hydride elimination of the beta-oxo-imidoyl palladium intermediates. Reaction of these relatively stable alpha-oxo ketenimines with nucleophiles suc ...

Amine synthesis via iron-catalysed reductive coupling of nitroarenes with alkyl halides

Xile Hu, Chi Wai Cheung

(Hetero)Aryl amines, an important class of organic molecules in medicinal chemistry, are most commonly synthesized from anilines, which are in turn synthesized by hydrogenation of nitroarenes. Amine synthesis directly from nitroarenes is attractive due to ...

Total asymmetric synthesis of glycomimetics and polypropionates of biological interest

Pierre Vogel

Using readily available chiral auxiliaries such as (+)- and (-)-camphanic acid, (R,R)- and (S,S)-tartaric acid derivatives (e.g. RADO(R)-COCl, SADO(R)-COCl) efficient diastereoselective syntheses of rare sugars and glycomimetics have been developed. They e ...
