Summary: Amine transaminases play a crucial role in the synthesis of chiral amines, which are essential building blocks in pharmaceuticals and fine chemicals. Advances in enzyme discovery, process engineering, and protein engineering have significantly enhanced the use of transaminases in organic synthesis. Enzymatic cascade engineering has emerged as an efficient and environmentally friendly approach for chiral amine synthesis, allowing the generation of valuable products from inexpensive starting materials. This review focuses on the utilization of amine transaminases in enzymatic and chemoenzymatic cascades for chiral amine synthesis.

Summary: A biocatalytic cascade for producing tert-butyl ((2R,4R)-2-methyltetrahydro-2H-pyran-4-yl)carbamate 6 has been demonstrated at a multikilogram scale. The process involves resolving a racemic ketone by selectively reducing the undesired ketone and then catalyzing enantioselective transamination to form the desired amine. The product is recovered after Boc protection in the aqueous reaction.

Summary: A one-pot chemoenzymatic sequential cascade was developed for the synthesis of chiral amines from alkynes. Gold catalysts were used to convert alkynes to ketones, followed by a transaminase catalyzed production of chiral amines with high yields and enantiomeric excess. Preparative scale synthesis of specific chiral amines showed high yields and enantiomeric excess.

Summary: A biocatalytic route towards N-alkanoyl-N-methylglucamides (MEGAs) and analogues was developed using a modified carboxylic acid reductase construct (CARmm-A). The selective formation of amide bonds was achieved without competing reactions. Reaction optimization resulted in reduced amine concentration requirements, enabling efficient amide formation. The wide substrate scope of CARmm-A was demonstrated through the synthesis of 24 commercially relevant amides.

Summary: An organocatalyzed one-pot sequential deracemization of aromatic ketones with a stereogenic center at the alpha-position was achieved through an acid-base strategy, in which enantioselective protonation reaction played a key role. This protocol provides enantioenriched ketones with up to 89% ee without isolating sensitive intermediates like silyl enolates. Water was found to be crucial in this process. This one-pot sequence serves as a valuable extension to previously reported chemically driven red-ox protocols, expanding the range of molecules eligible for deracemization.

Summary: In synthetic chemistry, the one-pot reaction has become an important method to achieve low environmental impact and economic efficiency. This method reduces energy and time consumption, avoiding lengthy purification processes. The proposed one-pot reaction involves the reaction of asymmetric aryl boronic acids with 3-azaarylpopenones containing a pyridine core, and it exhibits good catalytic effects.

Summary: A straightforward synthesis approach to chiral 1-aryl-2-aminoethanols via the one-pot asymmetric hydrogenation catalyzed by Ir catalyst was developed. This tandem process involves the in situ generation of alpha-amino ketones via the nucleophilic substitution of alpha-bromoketones with amines and the Ir-catalyzed asymmetric hydrogenation of ketone intermediates to provide diverse enantiomerically enriched beta-amino alcohols. The excellent yields and enantioselectivities (up to 96 % yield and up to >99 % ee) with a wide substrate scope in this one-pot strategy were obtained.

Summary: A novel series of enantiopure naphthalimide-cycloalkanediamine conjugates were designed, synthesized and evaluated for their in vitro cytotoxicity. The cytotoxicity of the compounds depended on the size of the cycloalkyl ring and length of the spacer, with no observed enantioselectivity. Compounds 22 and 23 were found to effectively induce G2/M arrest in the tested cell lines, despite a mild apoptotic effect.

Summary: mo-CECRs, bridging chemo- and bio-catalysis, can achieve chemical transformations with minimized purification steps and improved stereochemical control, but face challenges due to incompatibilities between different catalytic disciplines. Progress, challenges, and strategies in this area are discussed in this review, offering guidance for the design of new and robust mo-CECRs.

Summary: An efficient and selective N-functionalization of amides was reported via CuI-catalyzed Goldberg-type C-N coupling reactions in both Deep Eutectic Solvents (DESs) and water. The protocol showed promise for scaling up reactions without yield loss, recyclability of catalyst and solvent, and applicability in the synthesis of biologically active molecules.
