An efficient and flexible synthesis of a new class of chiral bifunctional NHC catalyst has been reported. These new imidazolylidene NHCs, bearing a (thio)urea function as a hydrogen bond donor promoted efficiently highly diastereoselective trans-cyclopentannulation of enals and enones in moderate to good yields (up to 69 % yield) along with excellent enantioselectivity (up to 96 % ee). This methodology could be applied to a large variety of substrates (30 examples).

The (Fmes)BH2 center dot SMe2 reagent (7) reacts sequentially with an acetylene and, e.g., xylylisonitrile in a convenient three-component reaction to give a series of unprecedented dihydro-1,3-azaborole derivatives 16. The tolane-derived example 16a was deprotonated and used as a ligand in organometallic chemistry. Compounds 16 served as the starting materials for the straightforward synthesis of various dihydro-1,3-azaborinine derivatives by treatment with an isonitrile. Several diaryldihydro-1,3 azaboroles showed interesting photophysical properties such as aggregation-induced emission and high fluorescence quantum yields.

The catalytic alkylation of ketones with alcohols via the hydrogen borrowing methodology (HB) has the potential to be a highly efficient approach for forming new carbon-carbon bonds. However, this transformation can result in more than one product being formed. The work reported here utilises bidentate triazole-carbene ligated iridium and rhodium complexes as catalysts for the selective formation of alkylated ketone or alcohol products. Switching from an iridium centre to a rhodium centre in the complex resulted in significant changes in product selectivity. Other factors – base, base loading, solvent and reaction temperature – were also investigated to tune the selectivity further. The optimised conditions were used to demonstrate the scope of the reaction across 17 ketones and 14 alcohols containing a variety of functional groups. A series of mechanistic investigations were performed to probe the reasons behind the product selectivity, including kinetic and deuterium studies.

A sustainable and practical protocol to prepare epoxides has been established by using air as the oxidant in the presence of K2CO3 in isopropylbenzene (CM) at 80-140 degrees C. The olefins are successfully converted into their corresponding epoxides in yields of up to 99%. CM and K2CO3 are reused in the scale-up recycling experiments. A reaction mechanism dominated by the radical pathway is proposed according to the control experiments and kinetic analysis.

A set of CB2R ligands, based on the thiophene scaffold, was synthesized and evaluated in in vitro assays. Compounds 8c-i, k, 1, bearing the 3-carboxylate and 2-(adamantan-1-yl)carboxamido groups together with apolar alkyl/aryl substituents at 5-position or at 4- and 5-positions of the thiophene ring possess high CB2R affinity at low nanomolar concentration, good receptor selectivity, and agonistic functional activity. The full agonist 8g, showing the best balance between receptor affinity and selectivity, was tested in vitro in an experimental model of allergic contact dermatitis and proved to be able to block the release of MCP-2 in HaCaT cells at 10 mu M concentration.

It is reported that cheap and easily available Hg(OTf)(2) can efficiently mediate the Sakurai-Hosomi reaction of N-tert-butyloxycarbonyl (Boc) amino sulfones, aldehydes, and alpha-fluoroalkyl ketones using allyltrimethylsilane, with the catalyst loading down to 0.5-5.0 mol%, enabling the facile access to synthetically valuable homoallylic alcohols or amines, respectively. A chemoselective 1,4-allylation of alpha,beta-unsaturated enones is also achieved under the catalysis of 5.0 mol% Hg(OTf)(2). In most cases, Hg(OTf)(2) exhibited intriguing properties superior to those of commonly used metal Lewis acids for such reactions, suggesting that mercury catalysis is worthwhile to explore.

Application In Synthesis of Chalcone. I found the field of Chemistry very interesting. Saw the article Radical C-N Borylation of Aromatic Amines Enabled by a Pyrylium Reagent published in 2020.0, Reprint Addresses Cornella, J (corresponding author), Max Planck Inst Kohlenforsch, Kaiser Wilhelm Pl 1, D-45470 Mulheim, Germany.. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone.

Herein, we report a radical borylation of aromatic amines through a homolytic C(sp(2))-N bond cleavage. This method capitalizes on a simple and mild activation via a pyrylium reagent ((Sc)Pyry-OTf) thus priming the amino group for reactivity. The combination of terpyridine and a diboron reagent triggers a radical reaction which cleaves the C(sp(2))-N bond and forges a new C(sp(2))-B bond. The unique non-planar structure of the pyridinium intermediate, provides the necessary driving force for the aryl radical formation. The method permits borylation of a wide variety of aromatic amines indistinctively of the electronic environment.

Fluxional chemical species such as bullvalene have been a valuable source of inspiration and fundamental insight into the nature of chemical bonds. A supramolecular analogue of bullvalene, i.e., a fluxional host-guest system, in which the ensemble of a well-defined host and guest is engaged in continuous, degenerate constitutional rearrangements, is still elusive, however. Here, we report experimental and computational evidence for guest-induced dynamic covalent rearrangements in the ammonium complexes of self-assembled orthoester cryptands. This unique behavior is made possible by the ammonium guest playing a dual role: it is sufficiently acidic to initiate dynamic covalent exchange reactions at the orthoester bridgeheads, and as a hydrogen bond donor it acts as a supramolecular template, governing the outcome of a multitude of possible intra- and intermolecular rearrangement reactions. One particularly striking example of inherent dynamic behavior was observed in host-guest complex [Na-4(+)subset of o-Me-2-2.1.1], which spontaneously rearranged into the larger and thermodynamically more stable complex [NH4+subset of o-Me-2-2.2.1], even though this process led to the formation of poor host o-Me-2-1.1.1 as a consequence of the excess of one subcomponent (diethylene glycol; 1 in our nomenclature). These inherently adaptive host-guest networks represent a unique platform for exploring the interrelationship between kinetic and thermodynamic stability. For instance, as a result of optimal NH4+ binding, complex [NH4+subset of o-Me-2-2.2.1] was found to be thermodynamically stable (negligible intermolecular rearrangements over weeks), whereas computational studies indicate that the compound is far from kinetically stable (intramolecular rearrangements).

An unprecedented triple catalytic, general ring-opening cyanation reaction of cyclopropyl ketones for the construction of gamma-cyanoketones is described. The key is to merge photoredox catalysis with Lewis acid catalysis and copper catalysis to enable the selective cleavage of the carbon-carbon bonds and the selective coupling of the generated radical and cyanide anion.

Chitosan microspheres modified by 2-pyridinecarboxaldehyde were prepared and used in the construction of a heterogeneous catalyst loaded with nano-Cu prepared by a reduction reaction. The chemical structure of the catalyst was investigated by Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and X-ray Photoelectron Spectroscopy (XPS). Under mild conditions, such as no ligand at room temperature, the catalyst was successfully applied to catalyze the borylation of alpha,beta-unsaturated receptors in a water-methanol medium, yielding 17%-100% of the corresponding beta-hydroxy product. Even after repeated use five times, the catalyst still exhibited excellent catalytic activity.
