✦ Synopsis


tetraones (mixed flavins) were prepared by the cyclizatron of 1,5=dihydro-8-[N-alkyl-N-(5-nitrouracil-6-yl)-amino-5-deazaflavins with Vilsmeier reagent.

The mixed flavins oxidized alcohol under neutral condition in sunlight and a remarkable autorecycling was observed.

Recently it was shown that 5-deazaflavins which are regarded as NAD' in flavin clothing are able to oxidize alcohols 1) and amines2) nonenzymatically and

## Abstract H~10~TTPR was prepared starting from terephthalaldehyde and characterized. Crystal structure of H~10~TTPR and an intermediate compound 11 were determined by X‐ray diffraction analysis. A quasi‐reversible redox wave at 1.15 V (vs. SCE) was observed for H~10~TTPR, indicating that it is a
