Amidation through carbamates
Elsevier (2009)N-Alkyl carbamates of primary amines are easily converted into amides under treatment with Grignard reagents. Consequently, primary amines can be converted into amides in a one-pot reaction through carbamate protection and ... -
Chiral palladacycles with N‑heterocyclic carbene ligands as catalysts for asymmetric hydrophosphination
American Chemical Society (2013)Design of chiral palladacycles with N-heterocyclic carbene (NHC) ligands has been carried out in good yields starting form commercially available enantiopure benzylamines. The methodology developed consists of the formation ... -
Cp*Ir(NHC) complexes as highly versatile and efficient catalysts for the cross-coupling of alcohols and amines
Wiley-VCH (2008-11-19)A comparative study on the catalytic activity of a series of Cp*Ir(NHC)Cl2 complexes in several C-O and C-N coupling processes implying hydrogen-borrowing mechanisms has been performed. The compound Cp*Ir(InBu)Cl2 (InBu ... -
Dynamic Kinetic Asymmetric Ring-Opening/Reductive Amination Sequence of Racemic Nitroepoxides with Chiral Amines: Enantioselective Synthesis of Chiral Vicinal Diamines
American Chemical Society (2013-05)We report a highly diastereoselective synthesis of vicinal diamines by the treatment of nitroepoxides with primary amines and then a reducing agent. When using a chiral primary amine, racemic nitroepoxides are transformed ... -
Selective reductive amination of aldehydes from nitro compounds catalyzed by molybdenum sulfide clusters
Royal Society of Chemistry (2017-07)Secondary amines are selectively obtained from low value starting materials using hydrogen and a non-noble metal-based catalyst. The reductive amination of aldehydes from nitroarenes or nitroalkanes is efficiently catalyzed ...
