چکیده انگلیسی

Imidazol-1-yl-acetic acid is introduced as a new, efficient and recyclable green bifunctional organocatalyst for the synthesis of 1,8-dioxooctahydroxanthenes under solvent-free conditions. This catalyst is water soluble and can be separated from the products by simple filtration. The filtrate can be evaporated to dryness and recrystallized from cool methanol to give the recovered catalyst. This organocatalyst was used for the synthesis of 1,8-dioxooctahydroxanthenes under solvent-free conditions and recycled up to 8 consecutive runs without any losing of its efficiency.

Imidazol-1-yl-acetic acid is introduced as a new, efficient and recyclable green bifunctional organocatalyst for the synthesis of 1,8-dioxooctahydroxanthenes under solvent-free conditions. Its bifunctional activity can efficiently catalyze this typical condensation reaction by simultaneous activation of both acidic and basic sites during the condensation progress.Figure optionsDownload as PowerPoint slide
