Highly efficient diastereoselective synthesis of novel spiro-furan derivatives catalyzed by MgO supported on periodic mesoporous organosilica based on ionic liquid

The synthesis of novel Spiro-furan derivatives via a three-component reaction of 1,3-dicarbonyl compounds, N-phenacyl pyridinium salts and accenaphthoquione. This reaction in the present of MgO nanoparticles on ionic liquid based periodic mesoporous organosilica (MgO@PMO-IL) were achieved in high efficiency with a simple work-up procedure and short reaction time, and the catalyst can be also recovered on efficiency reused in seven subsequent reaction conditions
