A facile and efficient strategy towards the novel tetra- and pentacyclic annulated coumarino-δ-sultam pyrrolidine, pyrrolizidine, pyrrolothiazole and isoxazolidine via intramolecular 1,3-dipolar cycloadditions of nitrones or azomethine ylides is described

The first examples of ring-closing metathesis (RCM) reactions on allyl- and vinylsulfonamide templates 1 and 2 catalyzed by the Grubbs ruthenium alkylidene 3 are described. The rate of cyclization of these reactions are sensitive to simple olefin substitu
