A novel, one-step synthesis of 5-deazaflavin developed, in which a [4+2]cycloaddition is presumably involved, to give the 5-deazaflavin derivative in moderate yield. This methodology was successfully applied to the stepwise preparation of its thio analogue, 5-deaza-10-thiaflavin, whose 1, 5-dihydro derivative was transformed into the corresponding sulfone in good yield.
