This article investigates an efficient and eco-friendly protocol for protecting amines and alcohols as important molecules in organic chemistry, using Fe3O4@MCM-41/Zr@Piperazine as a newly reported magnetic mesoporous nanostructured catalyst. Firstly, the protection of alcohols was developed through their transformation to trimethylsilyl ethers. Then this reagent was applied for the acceleration of the acetylation of […]
Sulfuric acid {[3-(3-silicapropyl)sulfanyl]propyl}ester (SASPSPE) is employed as a recyclable catalyst for the synthesis of α-amino nitriles. These syntheses were performed via a one-pot three-component condensation of aldehydes, amines, and trimethylsilyl cyanide under mild reaction conditions at room temperature. The catalyst could be recycled and reused several times without any loss of efficiency.
