2,4,5,8,9,11-Hexa-azapentaphene-1,3,10,12(2H,5H,8H,11H)-tetraones (angular 5-deazapteridino-deazaflavins) with strong oxidizing power

Abstract

Condensation of N,N′-dialkyl-p-phenylenediamines with 6-chloro-5-formyl-3-methyluracil, and cyclization of the resulting N,N′-dialkyl-N,N′-bis(3-methyluracil-6-yl)-p-phenylenediamines with Vilsmeier reagent gave the corresponding 2,4,5,8,9,11 -hexa-azapentaphene-1,3,10,12(2H,5H,8H,11H)-tetraones, which exhibited a very strong oxidizing ability towards cyclopentanol.
