A new, general, and convenient synthesis of 5-deazaflavins (5-deazaisoalloxazines) and bis-(5-deazaflavin-10-yl)alkanes
Abstract
The condensation of 6-substituted aminouracils or bis(uracil-6-ylamino)alkanes with o-halogeno-benzaldehydes in dimethylformamide led to the formation of the corresponding 5-deazafIavins or bis-(5-deazaflavin-10-yl)alkanes in a single step.
