Natural‐Inspired Engineered Microalgae With Selenium Enrichment Enabled Potent Anti‐Tumor Immunity
Advanced Science, EarlyView.Se‐Ssp was engineered as a potent immunomodulator for activating innate immunity via the TLR and cGAS‐STING pathways, therefore converting “cold” tumors into “hot” tumors to achieve high efficacy and long‐term therapeutic outcomes. ABSTRACT Immunotherapy has shed light on clinical oncology for several decades.

Ethyl 5-(4-Bromophenyl)-4-methyl-1H-pyrrole-2-carboxylate
Molbank, 2017 This note describes a sequence converting an oxime-substituted pyrrolidine into a trisubstituted pyrrole structure. The synthetic route is based on a double chlorination of the pyrrolidine substrate followed by the base induced formation of both an imine

Hydroxyl-Directed Nitrile Oxide Cycloaddition Reactions with Cyclic Allylic Alcohols
, 2016 Diastereoselective cycloaddition reactions between a nitrile oxide and cyclic allylic alcohols are reported. The products isolated are densely functionalized building blocks that are not otherwise easily accessed with existing methods and concepts ...

Dual Nickel/Photoredox‐Catalyzed Regio‐ and Enantioselective Alkenylation of Epoxides
Advanced Science, EarlyView.Ni/photoredox‐catalyzed stereoconvergent cross‐electrophile coupling of racemic epoxides with alkenyl bromides is described, affording β‐alkenyl products with up to 95% ee, excellent E‐selectivity, and complete regiocontrol. These versatile intermediates enable diverse chiral synthons; mechanistic studies suggest a halide ring‐opening followed by ...

Advanced Science, EarlyView.Time‐resolved synchrotron radiography reveals the internal evolution of electrochemical double‐layer capacitors under abusive overcharge. EDLCs are shown to follow a thermally driven failure pathway involving electrolyte decomposition, gas generation, and structural collapse, distinct from chemically driven thermal runaway effects of Lithium‐ion ...

Atmospheric oxidation of nitriles
, 1977 The reports of nitrile formation in actual and simulated auto emissions suggests a potential environmental hazard associated with the wide scale use of catalytic exhaust converters. Specifically, the atmospheric oxidation of nitriles is believed to occur via radical intermediates which can lead to both NO/sub x/ and CO production.

STEREOSELECTIVE INTRAMOLECULAR NITRILE OXIDE CYCLOADDITION TO CHIRAL ALLYL ETHERS
, 1987 Intramolecular nitrile oxide cycloaddition reactions on (Z)- and (E)-chiral allyl ethers occur with poor to good stereoselectivity (diastereoisomeric ratios up to 86: 14), which depends on the double bond configuration as well as on steric and ...

An anomalous hydration/dehydration sequence for the mild generation of a nitrile oxide [PDF]
, 2011 A nitrile oxide containing a carbamoyl group is readily generated upon the treatment of 2-methyl-4-nitro-3-isoxazolin-5(2H)-one with water under mild reaction conditions, even in the absence of special reagents.
