Notes:
To study π…π interactions of flavins of different redox states with π-electron donors and acceptors, the syntheses of compounds in which such π systems are linked to flavins by using the „cyclophane concept“ were attempted and partially achieved. The syntheses of the metacyclo-isoalloxazinophanes 1 and 2 are reported as well as the X-ray structure analysis of 2. The conversion of 1 or 2 to the benzoquinono-isoalloxazinophanes 3 or 4, respectively, was not achieved, obviously due to the specific sterical shielding of the methoxy groups in the isoalloxazinophanes. Benzoquinone-isoalloxazine systems in which the two components are linked by only one triethylene chain were obtained. Spectroscopic and electrochemical properties related to intramolecular interactions are reported.
