Epoxides and aziridines undergo nucleophilic ring-opening reactions with various inorganic azides yielding 2-azido alcohols and 2-azido amines, respectively. Nucleophilic ring opening of epoxides (e.g., 74) can be easily achieved by simple heating with sodium azide and ammonium chloride in a polar solvent (e.g., MeOH/H2O) for 148 hours to give the azides (e.g., 75) in good yields (Table 4).[‌97‌,‌98‌] The azide functionality is introduced at the sterically less hindered side of the ring with clean inversion of configuration. Substrates with one aromatic substituent preferably react at the activated side of the ring, but the regioselectivities achieved are rather modest.
