(matrix presented) The zirconium-mediated intramolecular ester transfer reaction of N-alkenyl carbamate derivatives proceeded to give α-substituted γ-aminobutyric acid (GABA) derivatives in good to excellent yields. Quenching experiments of the reaction mixture with iodine or O2 indicated the presence of a cyclopropane intermediate. The resulting iodide was converted to 2-substituted pyrrolidine-3-carboxylate and/or α-alkylidene-γ-aminobutyric acid derivatives in a stereospecific manner.

Ring-closing metathesis of ene-ynamide, which has alkene and ynamide moieties in a molecule, using a second-generation ruthenium carbene complex produced nitrogen-containing heterocycles, which have a dienamide moiety, in high yields. Diels-Alder reaction
A new, highly stereoselective approach to pyrrolidines via overall 5-endo-trig cyclisations of homoallylic tosylamides

Iodocyclisations of E-homoallylic tosylamides 7 lead to excellent yields of either 2,5-trans- or 2,5-cis-3-iodopyrrolidines (10 or 11), depending upon the reaction conditions.
