Summary: This passage describes a new technology for generating amide and peptide bonds from carboxylic acids and amines without traditional coupling reagents. The one-pot processes rely on the formation of thioesters using a simple dithiocarbamate, which are safe, green, and inspired by nature, and then converted to the desired functionality.

Summary: In this study, a simple, cheap, eco-friendly, and reusable glucose-based carbonaceous material (GCM) was synthesized as a catalyst for the synthesis of alpha-ketoamides through oxidative cross-dehydrogenative coupling (CDC) reaction. The GCM catalyst showed high efficiency in the one-pot two-step synthesis of alpha-ketoamides from alpha-ketoalcohols as well. The presence of carboxylic acid and hydroxyl groups in the carbonaceous framework of the GCM catalyst contributed to its acidic and oxidizing catalytic activity.

Summary: Amide synthesis is widely used in drug development and peptide synthesis, but waste elimination in this process has had limited success. Umpolung amide synthesis has been developed as a method for enantioselective synthesis, but it cannot forge N-aryl amides. This study presents a direct synthesis method for N-aryl amides using a simple Bronsted base as a promoter, using alpha-fluoronitroalkanes and N-aryl hydroxyl amines.

Summary: Chitooligosaccharide (COS), an emerging material carbohydrate polymer, was prepared using a microwave-assisted process. The COS was then used to synthesize COS-poly(ethylene glycol) diacrylate (PEGDA) derivatives through aza-Michael addition. The resulting COS-PEGDA hydrogels showed high biocompatibility and can be potentially used in biomedical applications.

Summary: Azobenzene derivatives are important molecular switches for biological and material science applications. This study synthesized and characterized two novel amides containing photoresponsive azobenzene units, investigating their photochemical properties through experimental and theoretical methods. The compounds underwent trans to cis isomerization under UV light, with quantum yields and reaction kinetics also analyzed. The presence of selected ions was found to influence the thermal relaxation and half-life time of the cis form.

Summary: Novel 18- and 23-membered diazomacrocycles were synthesized by diazocoupling of aromatic diamines with pyrrole under high dilution conditions, showing characteristics as chromogenic heavy metal ions receptors. These macrocycles exhibited selective and sensitive color and spectral response for lead(II) in acetonitrile mixtures with water. The introduction of a hydrocarbon residue as part of the macrocycle influenced the lead(II) binding, leading to the proposal of a selective and sensitive colorimetric probe for lead(II) in aqueous acetonitrile with a detection limit of 56.1 μg/L.
