N-Bromosaccharin/$Mg(ClO_4)_2$ is an effective and regioselective system for $\alpha}$-monobromination of 1,3-dicarbonyl compounds. A wide variety of $\beta}$-keto esters and 1,3-diketones in reaction with this system afforded a regioselectively $\alpha}$-monobrominated products. The bromination reaction can be conducted at 0-5 $^\circ}C$ either in solution or under solvent-free conditions.

The present invention is directed to heterocyclic SV40 Factor (LSF) inhibitors and their uses. In some implementations, the present invention discloses small-molecule compounds of Formula (I). In some implementations, the compounds of Formula (I) are used in methods for inhibiting LSF in a subject. In some implementations, the compounds of Formula (I) are used in methods for treating cancer in a subject.
A relay visible-light photoredox catalysis strategy has been accomplished. Three successive photoredox cycles (one oxidative quenching cycle and two reductive quenching cycles) are engaged in a single reaction with one photocatalyst. This strategy enables formal [4 + 1] annulation of hydrazones with 2-bromo-1,3-dicarbonyl compounds, which functionalizes three C–H bonds of hydrazones. This method affords

A new magnetic-nanoparticle-supported bromination reagent was synthesized by anchoring a 2,2′-bis[3-(triethoxysilyl)propyl]imidazolium-substituted diethylether bis(tribromide) onto the surface of γ-Fe2O3 nanoparticles and subsequently treating this new ionic liquid with bromine. The nanoparticle reagent was obtained with good loading levels and has been successfully used for the efficient bromination

approach toward N-acylated aminotriazoles is reported, enabling the compounds’ screening against FXIIa and thrombin. This approach afforded low-nanomolar FXIIa and thrombininhibitors with no off-targeting of the other tested serine proteases. Selected compounds were shown to be covalent inhibitors of FXIIa and demonstrated anticoagulant properties in vitro, influencing the intrinsic blood coagulation
