Chemical synthesis is the process by which one or more chemical reactions are performed with the aim of converting a reactant or starting material into a product or multiple products. Chemical synthesis is at the heart of much chemistry research as it is the basis for discovering compounds with new physical or biological properties.
The precision synthesis of cyclic polymers with ultrahigh molar mass (UHMM) and circularity is challenging. Now, a method that involves superbase-mediated living linear-chain growth followed by macromolecular cyclization triggered by protic quenching enables the on-demand production of UHMM cyclic polymers with a narrow dispersity and closed-loop chemical recyclability.
The idea that three different free radicals could be used together to carry out specific steps in a chemical reaction has long been implausible. A ‘radical sorting’ strategy now achieves this feat to make organic molecules.
Amides are important intermediates in organic chemistry and the pharmaceutical industry, but their low reactivity requires catalysts and/or harsh reaction conditions to esterify them. Here, the authors report a versatile and mild dimethyl sulfate-mediated reaction to activate and esterify C—N bonds, achieving up to 95% amide bond cleavage.
Considerable attention has been directed towards chiral nanocatalysts due to their significant role in facilitating asymmetric organic transformations. Here the authors highlight the recent advancements and notable examples in the field of chiral inorganic nanocatalysts.
The conversion of atmospheric N2 into NH3 under ambient pressure is highly interesting but very challenging. In this study, the authors present a tandem air-NOx and NOx-NH3 system that combines non-thermal plasma-enabled N2 oxidation with Ni(OH)x/Cu-catalyzed electrochemical NOx−reduction, resulting in a high NH3 yield from N2 under ambient pressure conditions.
Infrared colloidal quantum dots are interesting due to their low-cost fabrication and wavelength tunability for optoelectronic applications. Here, air-stable low-noise mid-infrared photodiode devices are fabricated using hole-doped Ag-HgTe nanocrystals.
Rhodium catalysts confined in zeolite pores exhibit high regioselectivity in the hydroformylation process of propene to high-value n-butanal, surpassing the performance of all heterogeneous and most homogeneous catalysts developed so far.
Poly-β-(1–6)-N-acetylglucosamine (PNAG) is an important vaccine target, but the impact of the number and position of free amine vs N-acetylation on its antigenicity is not well understood. Here, the authors report a divergent strategy to synthesize a comprehensive library of PNAG pentasaccharides, enabling the identification of enhanced epitopes for vaccines against Staphylococcus aureus including drug resistant strains.
The precision synthesis of cyclic polymers with ultrahigh molar mass (UHMM) and circularity is challenging. Now, a method that involves superbase-mediated living linear-chain growth followed by macromolecular cyclization triggered by protic quenching enables the on-demand production of UHMM cyclic polymers with a narrow dispersity and closed-loop chemical recyclability.
Irreproducible synthetic methods consume time, money, and resources. Here, we highlight the steps Nature Synthesis takes to help authors make their synthetic procedures as reproducible as possible.
The idea that three different free radicals could be used together to carry out specific steps in a chemical reaction has long been implausible. A ‘radical sorting’ strategy now achieves this feat to make organic molecules.
Chiral amines possessing a stereogenic carbon atom bearing three carbon substituents and one nitrogen substituent are challenging structural motifs to prepare enantioselectively. Now, such motifs have been accessed in high enantiopurities by asymmetric Cu-catalysed propargylic amination using sterically confined ligands.
