Tempo is a classic nitroxide radical and is a selective scavenger of mitochondrial ROS that dismutases superoxide in the catalytic cycle. Tempo induces DNA-strand breakage. Tempo can be used as an organocatalyst for the oxidation of primary alcohols to aldehydes. Tempo has mutagenic and antioxidant effects.

Abstract: Carbon-heteroatom bonds are of great importance due to their prevalence in pharmaceuticals, agrochemicals, materials, and natural products. Despite the effective use of metal-catalyzed crosscoupling reactions between sp2-hybridized organohalides and soft heteroatomic nucleophiles for carbon-heteroatom bond formation, the use of sp3-hybridized organohalides remain limited and the coupling with thiols remains elusive. Here, we report the coupling of sp3-hybridized benzyl or tertiary halides with soft thiol nucleophiles catalyzed by iron and extend the utility to alcohol and amine nucleophiles. The reaction is broad in substrate scope for both coupling partners and applicable in the construction of congested tri- and tetrasubstituted carbon centers as well as β-quaternary heteroatomic products. The synthetic utility is further emphasized by gram-scale synthesis and rapid herbicide library synthesis. Overall, we provide an efficient method to prepare pharmaceutically and materially relevant carbon-heteroatom bonds by expanding iron-catalyzed cross-coupling reactions to the coupling of sp3-hybridized organohalides with soft nucleophiles.

Abstract: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) papain-like cysteine protease (PLpro) represents one of only two essential cysteine proteases involved in the regulation of viral replication. It, therefore, qualifies as a promising therapeutic target for the development of antiviral agents. We identified a previously synthesized protease inhibitor, resulting from an earlier project, as a PLpro inhibitor and crafted a structure-activity relationship around the hit, leading to the more potent inhibitors ZHAWOC6941 (17h) and ZHAWOC25153 (17o) displaying IC50 values of 8 and 7 μM, respectively. The two compounds represent a new class of PLpro inhibitors and, with single‐digit micromolar IC50 values, are comparable to inhibitors found in the literature.

Abstract: In this study, we developed a simple transition-metal-free borylation reaction of aryl bromides. Bis-boronic acid (BBA), was used, and the borylation reaction was performed using a simple procedure at a mild temperature. Under mild conditions, aryl bromides were converted to arylboronic acids directly without any deprotection steps and purified by conversion to trifluoroborate salts. The functional group tolerance was considerably high. The mechanism study suggested that this borylation reaction proceeds via a radical pathway.
