Die Umsetzung von Donator‐substituierten 6‐Anilinouracil‐Derivaten 6 mit Vilsmeier Reagens ergibt in Abhängigkeit von der Substitution drei verschiedene Reaktionen: a) Donatoren in m‐Position führen regiospezifisch zu 8‐substituierten 5‐Deazaalloxazinen 8, b) mit Donatoren in p‐Position werden die 5‐Formyl‐Derivate 11 erhalten und c) mit dem starken m‐ständigen Dimethylamino‐Donator erfolgt zusätzliche
The condensation of 6-substituted-aminouracils with o-halogenobenzaldehydes in dimethylformamide led to the formation of the corresponding 5-deazaflavins in a single step.
6-取代的氨基尿嘧啶与邻卤代苯甲醛在二甲基甲酰胺中的缩合导致一步形成相应的5-脱氮黄素。

A series of 3-methyl-10-(substituted-phenyl)flavins was prepared and tested for antimalarial activity against the lethal parasite Plasmodium vinckei in mice. Several of these analogues were found to be effective antimalarial agents. A quantitative structure-activity relationship study was undertaken with 44 analogues and no satisfactory relationship could be established.
