Where Chemocatalysis Meets Biocatalysis: In Water

Harald Groeger et al.

Summary: Chemoenzymatic catalysis involves the merging of sequential reactions using both chemocatalysis and biocatalysis in a single reaction vessel. Running these reactions in water presents a challenge but offers many advantages, as most enzyme-catalyzed reactions occur in water, allowing for a wide synthetic diversity. This article presents creative approaches and solutions to combine chemo- and biocatalysis in water for synthetic purposes.

Lipase-catalyzed esterification in water enabled by nanomicelles. Applications to 1-pot multi-step sequences

Vani Singhania et al.

Summary: In an aqueous micellar medium, commercially available lipase catalyzes esterification with high selectivity in the absence of any co-factors, aided by only 2% designer surfactant TPGS-750-M. An unexpected finding shows that the simple additive PhCF3 can significantly expand the range of usable acid/alcohol combinations. This allows for multiple chemo- and bio-catalyzed 1-pot, multi-step reactions to be performed in water.

Tunable Unsymmetrical Ferrocene Ligands Bearing a Bulky Di-1-adamantylphosphino Motif for Many Kinds of Csp2-Csp3 Couplings

Guolin Xu et al.

Summary: In this study, a class of unsymmetrical bidentate ligands containing a di(1-adamantyl)phosphino group, named MPhos ligands, and their corresponding pre-catalysts were synthesized and fully characterized. These pre-catalysts were found to be effective for various C-sp(2)-C-sp(3) couplings, with good substrate scope and isolated yields. Additionally, the potential applications of these catalysts in active pharmaceutical ingredient synthesis were demonstrated using nine drug-like molecules.

Nanoparticle-catalyzed green synthetic chemistry ... in water ...

Bruce H. Lipshutz et al.

Summary: Pre-catalyst nanoparticles can catalyze various C-C bond-forming reactions in an aqueous medium with the presence of a designer synthetic surfactant. These reactions include Suzuki-Miyaura, Sonogashira, Mizoroki-Heck, and Negishi couplings, as well as others. Additionally, nitro group reductions and click reactions can also be catalyzed with these nanoparticles using small amounts of palladium and copper.

Impact of aqueous micellar media on biocatalytic transformations involving transaminase (ATA); applications to chemoenzymatic catalysis

Jade Dussart-Gautheret et al.

Summary: This study describes the surfactant-enabled asymmetric ATA-catalyzed reductive aminations in water, which enhance the conversion levels and enable 1-pot chemoenzymatic catalysis. The modified conditions involving both biocatalysis and chemocatalysis are environmentally responsible, indicating the potential of using chemistry in water.

Water-Sculpting of a Heterogeneous Nanoparticle Precatalyst for Mizoroki-Heck Couplings under Aqueous Micellar Catalysis Conditions

Haobo Pang et al.

Summary: Powdery nanoparticles with ppm levels of palladium undergo a morphological alteration upon exposure to water, leading to nanorods capable of catalyzing coupling reactions. The alteration is not limited to a specific phosphine ligand, and under aqueous micellar catalysis conditions, low residual palladium is observed in the product with a broad substrate scope.

Illuminating a Path for Organic Synthesis Towards Sustainability. No One Said It Would Be Easy ...

Bruce H. Lipshutz

Summary: The efforts to convert organic chemistry into a more sustainable discipline involve using technologies that make key reactions faster, better, and cheaper when run in recyclable water. This shift to water as a reaction medium is inevitable as it reduces pollution and conserves resources, while organic solvents continue to generate pollution and deplete finite reserves.

Nanomicelle-enhanced, asymmetric ERED-catalyzed reductions of activated olefins. Applications to 1-pot chemo- and bio-catalysis sequences in water

Nnamdi Akporji et al.

Summary: The presence of nanomicelles derived from the surfactant TPGS-750-M greatly enhances bio-catalytic reactions involving ene-reductases (EREDs) in tandem with chemo-catalysis in water. The transformations provided illustrate the variety of sequences now possible in 1-pot, serving as representative examples of this environmentally attractive approach to organic synthesis.
