Four compounds β‐sitosterol, β‐sitosterol‐3‐O‐β‐d‐glucopyranoside, ursolic acid and 4′,5,6‐trihydroxy‐3′, 7‐dimethoxyflavone were characterized from the dichloromethane extract of the aerial parts of Satureja khuzistanica (Lamiaceae), a native medicinal plant growing in Iran, on the basis of spectral analysis and comparing with the data in literature. The natural occurrence of these compounds can be conclusive for the chemotaxonomic characterization of the genus Satureja.

Rapid and efficient condensation reactions of 2‐aminothiophenol and 2‐aminophenol with various aldehydes were carried out using I₂ in solvent‐free conditions with or without microwave irradiation to afford the corresponding 2‐substituted benzothiazole and benzoxazole derivatives in good to excellent yields.

We applied magnetic NiFe ₂ O ₄ as a recoverable catalyst in the multicomponent reaction of substituted pyrroles. Magnetic NiFe ₂ O ₄ could be recovered from the reaction easily with an external magnet and reused nine times without significant activity loss. The yields are high.

Supported gold( iii ) on poly(ionic liquid) coated on magnetic nanoparticles produced a highly active, stable, recoverable and high loading for the synthesis of propargylamines (A ³ coupling reaction) under green conditions.
