Starting from lumiflavine and its 2-thio-analogue, the leukoflavine nucleus was obtained and stabilized by reductive acylation. The acyl-leuko-compounds seem to exhibit the possibility of substitution reactions in 2- and 4-positions. Several new lumiflavines were obtained, e. g. 4-thiolumiflavine and 2-desoxylumiflavine. The latter shows rather peculiar oxido-reductive properties which are discussed
