Abstract

Abstract To obtain 5-deazaflavins exhibiting red-shifted light absorption spectra, a number of C (8) substituted 5-deazaisoalloxazines were synthesized. This was accomplished a) by the oxidative cyclization of 5, 5′-arylmethylenebis (6-methylaminouracil) derivatives and b) by the cyclization of N-methylanilinouracil derivatives with a one-carbon reagent. The latter method led to the formation of impure products. Condensation and oxidation reactions ...
