1,3,9,1l,12,14-Hexazapentacene-2,4,8,10(1H,3H,9H,11H)-tetraones (double-headed 5-deazaflavins) with potential for oxido-reduction
Abstract
Condensation of 8-(substituted-amino)-1,5-dihydro-5-deazaflavins with 6-chloro-5-formyuracils, followed by dehydrogenation with diethyl azodicarboxylate gives the corresponding 1,3,9,1l,12,14-hexazapentacene-2,4,8,10(1H,3H,9H,11H)-tetraones, which exhibit strong oxido-reductive abilities.
