Treatment of 6-chloro-5-formyluracils with 2-benzylpyridines in dimethylformamide gave the corresponding 2H-pyrido<1',2':1,6>pyrido<2,3-d>pyrimidine-2,4(3H)diones which are a bent type of 5-deazaflavin.Similarly, treatment of 6-chloro-5-formyl-3-methyluracil with 2-aminopyridine gave a 6-azalog of the above bent 5-deazaflavin, 2H-pyrido<2',1':2,3>pyrimido<4,5-d>pyrimidine-2,4(3H)dione.These "bent 5-deazaflavins" showed oxidizing ability toward benzyl alcohol, cyclohexanol and benzylamine giving the corresponding carbonyl compounds.
