New Efficient RCM-Mediated Synthesis of Pyrrolidine Derivatives

K. C. Majumdar; Santanu Chakravorty; Abu Taher

Abstract Fast and effective ring-closing olefin metathesis (RCM) of diallyamine derivatives of coumarin, quinolone, pyridine, and substituted benzene, using first-generation RCM ruthenium-based catalyst, leads to corresponding pyrrolidine derivatives in 70–95% yields under very mild conditions.
