We report herein a nucleophilic carbene catalyzed redox azidation of epoxyaldehydes. The intermediate beta-hydroxy acyl azides undergo thermal Curtiusrearrangement followed by trapping with excess azide to form carbamoylazides or, in a complementary sequence, by the hydroxy group to form oxazolidinones. Both products are formed in modest to good yields and diastereoselectivities. The use of an enantioenriched
