    Notes: Summary In addition to a short communication describing the synthesis of 14,17-cyclonorcodeinone dimethylacetal1 a [1] we wish to present a simple alternative route together with a selection of some reactions depending on the great reactivity of this highly strained small ring system. The structure of1 a is established by X-ray analysis.

    Description / Table of Contents: Zusammenfassung Analog zu der kürzlich beschriebenen Synthese von Reissert-Epoxiden liefern 1-Acyl-2-alkyl-1,2-dihydrochinoline bei Behandlung mitm-Chlorperbenzoesäure diastereomerenreine Epoxide, die sich als Festsubstanzen außerordentlich stabil, in Lösung aber reaktiv gegenüber Nucleophilen erweisen. Da sie wertvolle Ausgangsverbindungen zu 1,2,3,4-substituierten Tetrahydrochinolinen mit definierter relativer Konfiguration darstellen, wurde die Stereochemie der Epoxide mittels Röntgenstrukturanalyse abgesichert.
    Notes: Summary Analogous to the recently described synthesis of Reissert epoxides the treatment of 1-acyl-2-alkyl-1,2-dihydroquinolines withm-chloroperoxybenzoic acid gave diasteromeric pure epoxides which are stable in crystalline state, but reactive in solution versus nucleophiles. Acting as useful intermediates to stereocontrolled functionalized 1,2,3,4-tetrahydroquinolines an X-ray analysis was performed to confirm the relative stereochemistry of the epoxides.
