An efficient reduction of double bonds conjugated with nitrile groups and acid or base sensitive furan rings with 2-phenylbenzimidazoline generated in situ has been successfully accomplished with high yields and excellent selectivity. The employed reducing agent was prepared in one step from ordinary chemicals. The other advantages of the presented method include mild and convenient reaction conditions, a benign and cost effective reagent, simple work-up and separation of the products. As this process does neither affect cyano and nitro groups nor furan rings, it is a valuable alternative when metal-catalyzed hydrogenations or borohydride reductions have failed.

Background: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of many malignant tumors. However, ICI-induced hyper-immune activation causes cardiotoxicity. Traditional treatments such as glucocorticoids and immunosuppressants have limited effectiveness and may even accelerate tumor growth.

The catalytic indirect reductive quenching method is facilitated by a combination of Ir(III) photoredox and sulfide dual-catalysis system. This study demonstrated a method for synthesizing multi-substituted furans by using a photoredox/sulfide dual-catalysis system. This method enables the synthesis of various furan derivatives, including spirofurans and phthalans.

The development of biobased polyesters with the combination of high UV shielding and degradability is a significant challenge. Herein, three 4-membered cyclic monomers containing two pyrrolidone and two furan rings were prepared by the aza-Michael addition of biobased bifuran diamine and dimethyl itaconate (DMI). They were available in melt polycondensation reactions with various diols to synthesize biobased polyesters.

Background: Real-world data on treatment patterns and clinical outcomes for newer drugs, including integrase strand transfer inhibitors, among older people with human immunodeficiency virus (PWH) are limited.
Methods: This cohort study included PWH enrolled in the Veterans Aging Cohort Study (VACS) who were prescribed a standard 3-drug antiretroviral therapy (ART) regimen containing dolutegravir (DTG), bictegravir (BIC), cobicistat boosted elvitegravir (EVG), raltegravir (RAL), or darunavir/ritonavir (DRV) plus 2 nucleoside reverse transcriptase inhibitors between January 1, 2014, and March 31, 2020, and who were ≥50 years at regimen initiation. The association between regimen and virologic effectiveness or discontinuation was assessed using logistic regression models with inverse probability of treatment weights.

Metal-organic frameworks (MOFs) are promising catalysts for the electrochemical oxygen evolution reaction (OER) due to their high surface area, tunable pore structures, and abundant active sites. Ligand engineering is an important strategy to optimize their performance. Here, we report the synthesis of NiFe-MOFs based on three different ligands: 1,4-terephthalic acid (BDC), 2,4-thiophene dicarboxylic acid (TDC), and 2,5-furandicarboxylic acid (FDC), to investigate the effects of heteroatom-based aromatic rings on OER performance.
