Enantioselective phosphine-catalyzed [6 + 1] annulations of α-allyl allenoates with 1,1-bisnucleophiles.

Organocatalytic annulations between allenes and bisnucleophiles represent one of the most convenient routes to various carbocycles and heterocycles. However, most examples are limited to the formation of five- and six-membered rings, probably owing to relatively easy handling of short-chained biselectrophiles. Here we report long-chained α-allyl allenoate-derived 1,6-biselectrophiles for the first time, enabling a phosphine catalyzed [6 + 1] annulation with readily available 1,1-bisnucleophilic reagents.

Mechanistic study indicated that this reaction involves a [4+2] Diels-Alder reaction and ring expansion of the bicyclo[4.

Metal Free Dötz-Type Aminobenzannulation Reaction via 1,1-Dipoles Cross-Coupling.

Aryl amines are of constant interest in organic synthesis owing to their ubiquity in natural products, pharmaceuticals, and organic materials. However, C-H amination or pre-functionalization frequently results in uncontrollable site selectivity, over activation and the generation of inseparable mixtures of regio-isomers. Here we present a novel metal free Dötz-type aminobenzannulation reaction that circumvents the selectivity issues inherent in aromatic chemistry, as well as the use of stoichiometric unstable organolithium reagents and toxic chromium complexes.

Bioactive NIR-II gold clusters for three-dimensional imaging and acute inflammation inhibition.

Strong fluorescence and high catalytic activities cannot be achieved simultaneously due to conflicts in free electron utilization, resulting in a lack of bioactivity of most near-infrared-II (NIR-II) fluorophores. To circumvent this challenge, we developed atomically precise Au clusters with strong NIR-II fluorescence ranging from 950 to 1300 nm exhibiting potent enzyme-mimetic activities through atomic engineering to create active Cu single-atom sites. The developed AuCu clusters show 18-fold higher antioxidant, 90-fold higher catalase-like, and 3-fold higher superoxide dismutase-like activities than Au clusters, with negligible fluorescence loss.

Betulinic acid (BA), an occurring pentacyclic triterpenoid, has various biological activities, such as anti-inflammation and antioxidation. Previous studies found that BA attenuated cyclophosphamide (CYP)-induced intestinal mucosal damage by inhibiting intestinal mucosal barrier dysfunctions and cell apoptosis. However, the effects and regulation mechanisms of BA on CYP-induced renal damage has not been reported in literature.

Suppression of endoplasmic reticulum stress-associated pathways and hepatocyte apoptosis participates in the attenuation of betulinic acid on alcohol-provoked liver injury in mice.

Endoplasmic reticulum stress (ERS) plays a vital role in the pathogenesis of the alcoholic liver disease (ALD). Betulinic acid (BA) has been reported to be effective in the attenuation of ALD; however, its role in ERS and associated stress-signaling pathways remains elusive. Here, we found that the BA pretreatment significantly reduced the alcohol-induced liver injury by decreasing the activities of serum alanine aminotransferase and aspartate aminotransferase, alleviating fat deposition and rupturing the ER in hepatocytes.
