A fluxional bis-monodentate ligand, based on the archetypal shape-shifting molecule bullvalene, self-assembles with M
There is growing interest in the biobased production of lipids from algae. These have a range uses including nutritional supplements and precursors to biodiesel. Single-cell thraustochytrids are especially attractive this regard that they can produce over 50% their weight as triglycerides. Furthermore, distribution saturated unsaturated triglycerides be modulated by changes strain variation fermentation conditions. Nonetheless, there remains need for versatile downstream processing enrich...
Sulfur-sulfur bonds are ubiquitous across broad classes of natural products, peptides and proteins, drug molecules, synthetic polymers materials. The ability to make break these in a controlled manner is critical for their many scientific technological applications. In this study, we report the discovery new unusual S-S metathesis reaction linear organic trisulfides. When exposed certain polar aprotic solvents, trisulfides were found undergo spontaneous metathesis, with equilibrium...
Boronate ester bullvalenes are now accessible in two to four operationally simple steps. This unlocks late-stage diversification through Suzuki cross-coupling reactions give mono-, di-, and trisubstituted bullvalenes. Moreover, a linchpin strategy enables preprogrammed installation of different substituents. Analysis solution phase isomer distributions single-crystal X-ray structures reveals that preference the crystal lattice is due general shape selectivity.
Acutely toxic substances such as cyanide salts and mercury metal are commonly used in gold mining. Mercury amalgamation artisanal mining is especially problematic the largest source of pollution on Earth. New strategies needed that do not rely for recovery. To address this problem, trichloroisocyanuric acid, activated by a halide catalyst, was to oxidatively dissolve metal. A polysulfide polymer sorbent then selectively bind gold, even complex mixtures. The can be recovered high purity...
Abstract A fluxional bis‐monodentate ligand, based on the archetypal shape‐shifting molecule bullvalene, self‐assembles with M 2+ (M=Pd or Pt ) to produce a highly complex ensemble of permanently coordination cages. Metal‐mediated self‐assembly selects for an 2 L 4 architecture while maintaining ligand complexity. second level simplification is achieved guest‐exchange; binding halides within cage mixture results in convergence species all four ligands present as “B isomer”. Within this...
The stereomutation of substituted bullvalenes is an inevitable consequence the valence isomerism that automerizes this unique fluxional hydrocarbon. introduction external stereogenicity in substituents expands reaction graphs and leads to a wealth complex diastereochemical relationships. In communication, we explore these possibilities prepare range stereochemically rich bullvalenes. This includes series disubstituted with two stereocenters as platform for fluxional, shape-diverse compound...
Synthetic approaches to bicyclo[4.2.0]octadiene natural products frequently employ the synthesis of linear tetraenes initiate a biosynthetic 8π/6π-electrocyclization cascade. This work forges functionalized in two steps from cyclooctatetraene. The versatility this method is demonstrated through product synthesis, including first total kingianic acid A and formal syntheses kingianins A, D, F cryptobeilic D ethyl ester. unexpected formation an E,E,Z,E-tetraene byproduct rationalized density...
The fluxional structure of bullvalene is expanded by the discovery a [5,5]-sigmatropic rearrangement dialkenyl substituted derivatives. This gives rise to tetrahydro-1,8-ethenoheptalenes (THEH), representing first examples this tricyclic scaffold. Variation substitution pattern alters product distribution, including one thermodynamically balanced between THEH and isomers. DFT calculations are used explore thermodynamic landscape reaction mechanism revealing pretransition state bifurcation...
