The study presents an efficient method for the N-alkylation of sulfonamides and amines using alcohols as alkylating reagents, catalyzed by manganese dioxide (MnO2) under aerobic and solvent-free conditions. This approach is a greener alternative to traditional methods, as it avoids the use of noble metal catalysts, preformed complexes, and inert atmosphere protection. The researchers found that MnO2 is a less toxic, readily available, and recyclable catalyst that can facilitate the reaction at mild temperatures without the need for high pressure or large excess amounts of reagents. The method was successfully applied to a variety of sulfonamides and amines, yielding good to high product yields. Additionally, the study explores the potential mechanism of the reaction, suggesting a process involving Mn-mediated alcohol oxidation, condensation, transfer hydrogenation, and regeneration of the aldehyde, which completes the catalytic cycle. The developed method simplifies operation and workup procedures and may serve as a promising alternative to existing N-alkylation methods.
The study presents an efficient, green, and reusable catalytic system using KF/Al2O3 for the solvent-free synthesis of N-alkyl derivatives of sulfonamides via Michael reactions. The process is conducted under microwave irradiation without the need for organic solvents, making it environmentally friendly and cost-effective. The researchers optimized the reaction conditions and found that the use of KF/Al2O3 and tetrabutylammonium bromide (TBAB) significantly improved the yield and selectivity of the desired N-alkylated sulfonamides. The method was effective with various α,β-unsaturated esters and sulfonamides, demonstrating broad applicability. The catalyst could be reused multiple times after simple washing, showing its potential for industrial applications. The study emphasizes the importance of green chemistry practices and the role of microwave irradiation in accelerating reaction rates and improving outcomes.
The research focuses on the development of potent and selective human β3 adrenergic receptor (AR) agonists, specifically tetrahydroisoquinoline derivatives containing a benzenesulfonamide moiety, for potential use in treating obesity. The study aimed to improve the selectivity and potency of these compounds over binding to and activation of β1 and β2 ARs. Key chemicals included trimetoquinol (TMQ), a potent human β3 AR agonist with limited selectivity, and various derivatives such as biphenyl, naphthyl, and aryloxy compounds. The researchers synthesized and tested several derivatives, finding that the 4,4-biphenyl derivative 9 was a potent full agonist with an EC50 of 6 nM and showed >300-fold selectivity over binding to β1 and β2 ARs. The naphthyloxy compound 18 exhibited excellent selectivity for the β3 AR, with an EC50 of 78 nM and >1000-fold selectivity over binding to β1 and β2 ARs. The study concluded that these derivatives represent a significant advancement in the design of structurally distinct human β3 AR agonists, potentially offering therapeutic benefits for obesity treatment.
