Abstract
This account summarizes the Njardarson group ring expansion journey from early vinyl oxirane explorations to the latest vinyl oxetane ring expansion discoveries. The evolution of the program and incredible success of Cu(hfacac)2 as catalyst is detailed. Application of these new ring expansion reactions to natural product, pharmaceutical and commodity chemical targets is discussed as well as our intriguing mechanistic journey and interesting entry into the world of chiral counterion catalysis.

- 34 Although the Aggarwal approach is a step shorter than Ellman’s for accessing chiral sulfonamides, it is worth noting that the sulfonamide imines needed are harder to make and far less stable than the sulfoxide imines, which are easily formed and readily purified by chromatography.
