Evidence is presented for a synchronous mechanism of the acid-catalyzed 1,2-rearrangement of 2-methoxyisoxazolidine-2,3-dicarboxylic acid ester with migration of the ester group to the N-atom.It was shown that the reaction is suppressed in the presence of an external nucleophile or a reducing agent.The regularities found were used to explain the transformations of bicyclic systems with an -ONO-fragment.
