Abstract
Chiral amines are key structural motifs present in a wide variety of natural products, drugs, and other biologically active compounds. During the past decade, significant advances have been made with respect to the enantioselective synthesis of chiral amines, many of them based on catalytic asymmetric hydrogenation (AH). The present review covers the use of AH in the synthesis of chiral amines bearing a stereogenic center either in the α, β, or γ position with respect to the nitrogen atom, reported from 2010 to 2020. Therefore, we provide an overview of the recent advances in the AH of imines, enamides, enamines, allyl amines, and N-heteroaromatic compounds.

Abstract
A synthetic approach to a new class of allyl nitro derivatives is reported. (2-Acetoxy)allyl nitro compounds have been prepared for the first time in a four-step procedure by a preliminary reaction of nitroalkanes with 2-(phenylselenyl)acetaldehyde. After the acetylation of the obtained nitro alcohols, the unsaturation is installed by an oxidation reaction involving the phenylselenyl group followed by a thermal elimination. The oxidation process is accomplished under flow conditions ensuring a notable lowering of overoxidation by products observed in batch.

Abstract
Thiolate-capped RhNPs in imidazolium-based ionic liquids were synthesized from [Rh(μ-SR)(COD)]2 dimmers under H2 pressure without external addition of ligand stabilizers, preserving thiolate integrity on the nanoparticle surface. This nanoparticulated systems showed a remarkable selectivity that led to their application in the one pot reductive N-alkylation to produce amines.

Abstract
A range of β-keto-γ-acetal enamides has been synthesized and transformed into the corresponding enantioenriched α-acetal-β'-amino ketones with enantioinductions of up to 99% by using rhodium/QuinoxP*-catalyzed enantioselective hydrogenation under mild conditions. This method also proved to be highly chemoselective toward the reduction of the C-C double bond.

Abstract
![]()
Oxime-directed
catalytic asymmetric hydroboration is diverted to
catalytic asymmetric hydrogenation (CAH) upon the addition of a proton
source, such as MeOH, or by running the reaction under a hydrogen
atmosphere. A borane (e.g., pinacolborane) is required to promote
CAH. Tri- and tetrasubstituted alkenes, including the challenging
all-alkyl tetrasubstituted alkenes, undergo CAH with enantiomer ratios
(er) as high as 99:1. The mild reaction conditions, i.e., ambient
temperature, moderate reaction times, and the need for only a slight
excess of H2, contrast those used in most state-of-the-art
catalysts for related substrates.
