The mechanisms of the Ugi and Ugi–Smiles reactions were investigated by using finely selected reaction conditions that allowed all of the intermediates to be “fish-out” and characterized by ESI-MS/MS. New insight into the Ugi and Ugi–Smiles reaction mechanisms is provided without using charge-tagged reagents.

Abstract

The mechanisms of the Ugi and Ugi–Smiles reactions were investigated by using finely selected reaction conditions that allowed all of the intermediates to be “fish-out” and characterized by ESI-MS/MS. New insight into the Ugi and Ugi–Smiles reaction mechanisms is provided without using charge-tagged reagents. Characterization of the isomeric species of the Mumm rearrangement in the gas phase was performed by using MS/MS.
