New routes to alkoxymaleic anhydrides 1a/b have been described in good yields via base-induced chemoselective vinylic substitution of bromo atom in bromomaleimide 4 with alkanols, and base-induced oxa-Micahel addition of alkanols to dialkyl acetylene-dicarboxylates 8a/b as key steps. An unusual acyl exchange in the conversion of 6a/b to 1a/b under very simple and mild reaction conditions is noteworthy.
