Sterically Invariant Carborane-Based Ligands for the Morphological and Electronic Control of Metal-Organic Chalcogenolate Assemblies

Autor: Harrison Mills, Christopher Jones, Kierstyn Anderson, Austin Ready, Peter Djurovich, Saeed Khan, J. Nathan Hohman, Hosea Nelson, Alexander Spokoyny

Herein, we report the use of sterically invariant carborane-based chalcogenols, containing exopolyhedral B-Se or B-S bonds, as ligands for the formation of photoluminescent copper(I)-based metal-organic chalcogenolate assemblies (MOCHAs). We show tha

MicroED Elucidation of Diverse Solid-State Packing in a Family of Electron-Deficient Expanded Helicenes

Autor: Adrian Samkian, Gavin R. Kiel, Christopher G. Jones, Harrison Bergman, Julia Oktawiec, Hosea Nelson, T. Don Tilley

Solid-state packing plays a defining role in the properties of a molecular organic material, but it is difficult to elucidate in the absence of single crystals that are suitable for X-ray diffraction. Here, we demonstrate the coupling of divergent sy

Chemocatalytic Amplification Probes Enable Transcriptionally-Regulated Au(I)-Catalysis in E. coli and Sensitive Detection of SARS-CoV-2 RNA Fragments

Autor: Sydnee Green, Benjamin Wigman, Sepand Nistanaki, Hayden Montgomery, Christopher G. Jones, Hosea Nelson

The union of transition metal catalysis with native biochemistry presents a powerful opportunityto perform abiotic reactions within complex biological systems.(1,2) However, several chemicalcompatibility challenges associated with incorporating react

Terpene Tail-to-Head Polycyclization Mediated by Small Molecule Catalysts: A Weakly-Coordinating Anion Approach

Autor: Jessica Burch, Alex L. Bagdasarian, Tanin Hooshmand, Hosea Nelson

Biomimetic total synthesis has played a pivotal role in the development of synthetic organic chemistry. In particular, efforts aimed at mimicking the head-to-tail (HT) cation–π cyclization cascades invoked in terpene biosynthesis, such as those ca

Dewar Heterocycles as Versatile Monomers for Ring-Opening Metathesis Polymerization

Autor: Sepand Nistanaki, Hosea Nelson

We report the utility of readily available heterocycles as precursors to unique ring-opening metathesis polymerization (ROMP) monomers. Photochemical valence isomerization reactions of pyridones, dihydropyridines, and pyrones dearomatize the parent h

Regulating Transition Metal Catalysis Through Interference by Short RNAs

Autor: Sydnee Green, Hayden Montgomery, Tyler R. Benton, Neil Chan, Hosea Nelson

Here we report the discovery of a Au(I)-DNA hybrid catalyst that is compatible with biological media and whose reactivity can be regulated by small complementary nucleic acid sequences. The development of this catalytic system was enabled by the disc

Strong Bases and Weak Anions in Catalytic C–H Insertion Reactions of Vinyl Carbocations

Autor: Benjamin Wigman, Stasik Popov, Alex L. Bagdasarian, Brian Shao, Tyler R. Benton, Chloé G. Williams, Steven P. Fisher, Vincent LaVallo, Kendall N. Houk, Hosea Nelson

Here we report the surprising discovery that high-energy vinyl carbocations can be generated under strongly basic conditions, and that they engage in intramolecular sp3 C–H insertion reactions through the catalysis of commercially available weakly

A Concise Total Synthesis of (±)-Vibralactone

Autor: Sepand Nistanaki, Luke A. Boralsky, Roy D. Pan, Hosea Nelson

Disclosed is a four-step synthesis of (±)-vibralactone, a biologically active terpenoid natural product. A key photochemical valence isomerization of 3-prenyl-pyran-2-one forges both the all-carbon quaternary stereocenter and the β-lactone at an ea
