Iridium-Catalyzed Acid-Assisted Hydrogenation of Oximes to Hydroxylamines

Nicolai Cramer, Josep Más-Roselló

We found that cyclometalated cyclopentadienyl iridium(III) complexes are uniquely efficient catalysts in homogeneous hydrogenation of oximes to hydroxylamine products. A stable iridium C,N-chelation is crucial, with alkoxy-substituted aryl ketimine ligands ...

Iridium-catalyzed acid-assisted asymmetric hydrogenation of oximes to hydroxylamines

Nicolai Cramer, Josep Más-Roselló

Asymmetric hydrogenations are among the most practical methods for the synthesis of chiral building blocks at industrial scale. The selective reduction of an oxime to the corresponding chiral hydroxylamine derivative remains a challenging variant because o ...

Catalytic Reduction of Oximes to Hydroxylamines: Current Methods, Challenges and Opportunities

Nicolai Cramer, Josep Más-Roselló

Catalytic reduction of oximes represents a direct efficient approach to synthesize valuable hydroxylamine derivatives. However this transformation presents significant challenges: oximes are hard to reduce and, if reactive, reductive cleavage of the weak N ...

Chiral Cyclopentadienyl Ligands: Design, Syntheses, and Applications in Asymmetric Catalysis

Ana Garcia Herraiz, Nicolai Cramer, Benoît Daniel Bertrand Audic, Josep Más-Roselló, Aragorn Nathan Laverny

The creation of new chiral ligands capable of providing high stereocontrol in metal-catalyzed reactions is crucial in modern organic synthesis. The production of bioactive molecules as single enantiomers is increasingly required, and asymmetric catalysis w ...
