ChemInform Abstract
The 2-imino-1,3-dioxolanes (I) react with the oxiranes (II) in the presence of aluminum trichloride to produce the oxazolidinones (IV), together with the oxirane (V). The mechanism is discussed to proceed via the spirocyclic intermediate (III). In one case, namely by reaction of the iminodioxolane (VI) with the oxirane (VII), the spiro compound (VIII) is obtained in good yield.
