Abstract Chiral amines are valuable building blocks in the manufacture of agrochemicals, pharmaceuticals, natural products, fine chemicals, functional materials among others. Compared to asymmetric hydrogenation imines/enamides and biocatalytic/organocatalytic reductive amination, transition metal catalyzed direct hydrogenative amination reactions (DAHA) using molecular dihydrogen as reductant highly economical, atom and/or step‐efficient thus attractive for researchers from both industry academia. In previous reviews, catalysts/methods development, applications synthesis pharmaceuticals [N] source were summarized discussed. this review, we summarize discuss ketone substrates scope upon utilizing state‐of‐the‐art catalysts. The substrate limitations, potential key mechanisms also critically concluded.

Abstract This review analyzes a development in biochemistry, enzymology and biotechnology that originally came as surprise. Following the establishment of directed evolution stereoselective enzymes organic chemistry, concept partial or complete deconvolution selective multi‐mutational variants was introduced. Early experiments led to finding mutations can interact cooperatively antagonistically with one another, not just additively. During past decade, this phenomenon shown be general. In some studies, molecular dynamics (MD) quantum mechanics/molecular mechanics (QM/MM) computations were performed order shed light on origin non‐additivity at all stages an evolutionary upward climb. Data used construct unique multi‐dimensional rugged fitness pathway landscapes, which provide mechanistic insights different from traditional landscapes. Along related line, biochemists have long tested result introducing two point enzyme for reasons, followed by comparison respective double mutant so‐called cycles, showed only additive effects, but more recently also uncovered cooperative antagonistic non‐additive effects. We conclude suggestions future work, call unified overall picture epistasis.

The development of catalysts serves as the cornerstone innovation in synthesis, exemplified by recent discovery photoenzymes. However, repertoire naturally occurring enzymes repurposed direct light excitation to catalyze new-to-nature photobiotransformations is currently limited flavoproteins and keto-reductases. Herein, we shed on imine reductases (IREDs) that remote C(sp3)–C(sp3) bond formation, providing a previously elusive radical hydroalkylation enamides for accessing chiral amines (45 examples with up 99% enantiomeric excess). Beyond their natural function catalyzing two-electron reductive amination reactions, upon visible-light or synergy synthetic photoredox catalyst, IREDs are tune non-natural photoinduced single-electron processes. By conducting wet mechanistic experiments computational simulations, unravel how engineered intermediates toward productive enantioselective pathway. This work represents promising paradigm harnessing nature's asymmetric transformations remain challenging through traditional chemocatalytic methods.

Axially chiral biaryl compounds are ubiquitous scaffolds in natural products, bioactive molecules, ligands and catalysts, but biocatalytic methods for their asymmetric synthesis limited. Herein, we report a highly efficient route the atroposelective of biaryls by dynamic kinetic resolution (DKR). This DKR approach features transient six-membered aza-acetal-bridge-promoted racemization followed an imine reductase (IRED)-catalyzed stereoselective reduction to construct axial chirality under ambient conditions. Directed evolution IRED from Streptomyces sp. GF3546 provided variant (S-IRED-Ss-M11) capable catalyzing process access variety aminoalcohols high yields excellent enantioselectivities (up 98 % yield >99 : 1 enantiomeric ratio). Molecular dynamics simulation studies on S-IRED-Ss-M11 revealed origin its improved activity atroposelectivity. By exploiting substrate promiscuity IREDs power directed evolution, our work further extends biocatalysts' toolbox challenging axially molecules.

Although amine dehydrogenases (AmDHs) are emerging as attractive biocatalysts for chiral synthesis, their synthetic application in structurally diverse arylamines remains challenging, given the limited substrate acceptance. Substrate walking is an effective coevolution strategy to confer targeted acceptance enzyme through a stepwise mutagenesis landscape adaptation. Here, based on conventional strategy, we report shield machine-like quickly evolve F-BbAmDH from Bacillus badius accessing difficult-to-aminate fused-ring and linked-ring aryl ketones.

Axially chiral biaryl benzylamines are present in numerous natural products, pharmaceuticals, ligands, and catalysts. However, the direct catalytic synthesis of these functional molecules using a robust strategy remains formidable challenge. Reductive amination desymmetrization dialdehydes offers powerful approach for construction axially but suffers from extensive undesirable side reactions. Herein, we engineered ancestral imine reductases to enable reductive dialdehydes, allowing wide range with up 99% conversion enantiomeric excess (ee). The ratio product byproducts was 97:3 over 90:10 most cases. This work presents an alternative accessing will stimulate development associated bioactive catalysts/ligands.
