Iridium-Catalyzed Reductive Nucleophilic Addition to Secondary Amides
Takahashi, Yoshito,Yoshii, Risa,Sato, Takaaki,Chida, Noritaka
, p. 5705 - 5708 (2018)
An iridium-catalyzed reductive nucleophilic addition to secondary amides is reported. After the iridium-catalyzed reduction, the resulting imines can undergo the Strecker reaction, the Mannich reaction, allylation, and [3 + 2]-cycloaddition. The method sh
Hydrogenation of β-N-substituted and β-N,N-disubstituted enamino esters in the presence of iridium(I) catalyst

experimental part, p. 2627 - 2633 (2009/12/06)
Several new β-amino esters were prepared in two simple steps from β-keto ester derivatives and primary and secondary amines under mild conditions. The hydrogenation of various enamino esters was performed at 50°C in the presence of iridium catalysts. The new β-N-substituted amino esters were isolated in high yields.

Practical, highly enantioselective chemoenzymatic one-pot synthesis of short-chain aliphatic β-amino acid esters
Wei?, Markus,Gr?ger, Harald
experimental part, p. 1251 - 1254 (2009/09/06)
A practical, highly enantioselective method for the synthesis of short-chain aliphatic β-amino acid esters was developed starting from prochiral and easily accessible substrates. This chemoenzymatic approach is based on a nonenzymatic aza-Michael addition
ZrOCl2·8H2O on montmorillonite K10 accelerated conjugate addition of amines to α,β-unsaturated alkenes under solvent-free conditions
Hashemi, Mohammed M.,Eftekhari-Sis, Bagher,Abdollahifar, Amir,Khalili, Behzad
, p. 672 - 677 (2007/10/03)
At room temperature, ZrOCl2·8H2O on montmorillonite K10 efficiently catalyzes conjugate addition of amines to a variety of conjugated alkenes such as α,β-unsaturated carbonyl compounds, carboxylic esters, nitriles and amides under solvent-free conditions. The catalyst can be recycled for subsequent reactions without any appreciable loss of efficiency.
Solvent-free stereoselective synthesis of β-aryl-β-amino acid esters by the Rodionov reaction using microwave irradiation
Romanova,Gravis,Kudan,Bundel'
, p. 26 - 27 (2007/10/03)
A rapid method for the title synthesis of β-aryl-β-amino acid esters was developed, and the absolute configurations of newly formed C-3 chiral centres in the major and minor diastereomers of the resulting ethyl N-[(S)-α-methylbenzyl]-β-amino-β-phenyl-propionate were determined.
