New N- and O-arylations with phenylboronic acids and cupric acetate

A new method of arylating N-H and O-H containing compounds at room temperature with phenylboronic acids and cupric acetate in the presence of a tertiary amine promoter is described. Substrates include phenols, amines, anilines, amides, imides, ureas, carbamates, and sulfonamides.

Synthesis of N-aryl-2-oxazolidinones from cyclic carbonates and aromatic amines catalyzed by bio-catalyst

A convenient and effective method of synthesizing 3-aryl-2-oxazolidinones from cyclic carbonates and aryl amines catalyzed by bio-catalyst adenine in the presence of Et3N under solvent-free conditions is described. The protocol is suitable for the wide scope of substrates, e.g. cyclic carbonates with or without substitutes, and aryl amines with either electron-withdrawing or electron-donating group. The products were obtained in good to excellent yields under the optimal conditions, even in steric hindered cases. The effect of reaction time, temperature, loading of catalyst, and amount of starting materials in the reaction were investigated, and the reaction mechanism is discussed.

A straightforward one-pot synthesis of bioactive: N -aryl oxazolidin-2-ones via a highly efficient Fe3O4@SiO2-supported acetate-based butylimidazolium ionic liquid nanocatalyst under metal- and solvent-free conditions

In the present study, we report the fabrication and characterization of novel acetate-based butylimidazolium ionic liquid immobilized silica-coated magnetic nanoparticles (IL-OAc@FSMNP). The synthesized nanocomposite proves its supremacy as an environmentally benign catalyst in the reaction of aniline and its derivatives with ethylene carbonate to form bioactive N-aryl oxazolidin-2-ones under metal-, ligand-, and solvent-free conditions. The catalyst offers excellent assemblies of hydrogen-bond donors and acceptors, which activate the substrates, thereby delivering good-to-excellent product yields with a conversion and selectivity of more than 99%. Additionally, mild reaction conditions, wide substrate scope, effortless catalytic recovery and recyclability of the catalyst up to eight consecutive cycles offer the potential for scale-up in various pharmaceutical applications.
