Green Synthesis and Biological Aspect of Seven-Membered Azepine Hybrids: A Recent Update".

Seven-membered nitrogen-containing heterocycles, particularly azepine-based compounds, represent an intriguing class of molecules with vast arrays of applications. These compounds have garnered considerable attention in synthetic and medicinal chemistry due to their non-planar, non-aromatic features, which offer structural flexibility and diversity to design new drugs with improved pharmacological properties. This review summarizes the recent advances in the synthesis of azepine derivatives, including eco-friendly methodologies that align with the principles of green chemistry, which emphasize atom economy, sustainability, and waste reduction.

Water-assisted cascade synthesis of trifluoromethylated dipyridodiazepinone analogues: and antibacterial studies.

A base-promoted palladium-catalyzed cascade reaction is described to access trifluoromethylated dipyridodiazepinone derivatives in an aqueous system (1,4-dioxane-HO). This methodology uses simple chemicals, has a broad substrate scope, is waste minimized (-factor = 0.3-0.
