Facile diastereoselective access to functionalized oxazol-5-ones and dihydroimidazoles was accomplished through base-promoted intramolecular amidolysis and methoxide-assisted tandem intramolecular amidolysis/ring opening/intramolecular cyclization, respectively, of C-3-functionalized azetidin-2-ones.
