Synthesis of new diastereoselective spiroheterocycles based on dual function of β- diketones

Abstract

In this research, based on the dual function of b-diketones, some new spirocarbocycle compounds were prepared using NiFe2O4 MNPs as a heterogeneous and recyclable nanocatalyst. In the present work, some novel and valuable products were completely achieved diastereoselective in a simple, efficient and productive protocol and with using green solvent and available starting materials.
