Synthesis of 2-Substituted Tryptamines via Cyanide-Catalyzed Imino-Stetter Reaction

Herein, we describe the development of a two-step protocol for the synthesis of 2-substituted tryptamine derivatives from 2-aminocinnamyl nitriles and aldehydes. The cyanide-catalyzed imino-Stetter reaction of 2-aminocinnamyl nitriles and aldehydes provided 2-substituted indole-3-acetonitrile derivatives. Subsequent reduction of the nitrile group afforded the desired 2-substituted tryptamine derivatives. The utility of this protocol was demonstrated in the synthesis of a potential inhibitor of 15-lipoxygenase. Furthermore, the resulting 2-substituted indole-3-acetonitriles were converted to several 2,3-disubstituted indole derivatives upon transformation of the nitrile group into other functional groups.

A Nanomechanical Study on Deciphering the Stickiness of SARS-CoV-2 on Inanimate Surfaces

The SARS-CoV-2 virus that causes the COVID-19 epidemic can be transmitted via respiratory droplet-contaminated surfaces or fomites, which urgently requires a fundamental understanding of intermolecular interactions of the coronavirus with various surfaces. The corona-like component of the outer surface of the SARS-CoV-2 virion, named spike protein, is a key target for the adsorption and persistence of SARS-CoV-2 on various surfaces. However, a lack of knowledge in intermolecular interactions between spike protein and different substrate surfaces has resulted in ineffective preventive measures and inaccurate information. Herein, we quantified the surface interaction and adhesion energy of SARS-CoV-2 spike protein with a series of inanimate surfaces via atomic force microscopy under a simulated respiratory droplet environment. Among four target surfaces, polystyrene was found to exhibit the strongest adhesion, followed by stainless steel (SS), gold, and glass. The environmental factors (e.g., pH and temperature) played a role in mediating the spike protein binding. According to systematic quantification on a series of inanimate surfaces, the adhesion energy of spike protein was found to be (i) 0-1 mJ/m(2) for hydrophilic inorganics (e.g., silica and glass) due to the lack of hydrogen bonding, (ii) 2-9 mJ/m(2) for metals (e.g., alumina, SS, and copper) due to the variation of their binding capacity, and (iii) 6-11 mJ/m(2) for hydrophobic polymers (e.g., medical masks, safety glass, and nitrile gloves) due to stronger hydrophobic interactions. The quantitative analysis of the nanomechanics of spike proteins will enable a protein-surface model database for SARS-CoV-2 to help generate effective preventive strategies to tackle the epidemic.

Monoanion-regulated high-voltage nitrile-based solid electrolyte with compatible lithium inertness

High-voltage plastic solid electrolytes (PSEs) have emerged as appealing candidates for energy-dense Li-metal batteries, but their inherent instabilities toward reductive Li anodes pose a hurdle to practical application. Herein, we report the monoanion-regulated design of a lithium-inert, high-voltage PSEs, demonstrated with a nitriledecorative PSEs (CN-PSEs) driven by BF2C2O4- monoanion. The monoanion-induced shielding layer helps to smooth lithium deposition, suppress the plastic matrix depletion, and thus retain robust Li/CN-PSEs interface even after cycling up to 1600 h in Li/Li cell, while the high-polarity nitrile group can support ion conduction and high-voltage tolerance up to 5.25 V. Benefit from the synergy, all-solid-state batteries with CN-PSEs show the superior cycling (300 cycles at 25 degrees C). This effective strategy provides a novel design principle for high-voltage PSEs to address the poor reductive stability.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 590-17-0 help many people in the next few years. Category: nitriles-buliding-blocks.
