Synthesis of New Hydroxybenzo[a]carbazoles
Synthesis, 2008An investigation of the alkylation sites of 4,7-dihydroxybenzo[ A]pyrrolo[3,4- C]carbazole-1,3(2 H,8 H)-dione,as well as the site of reduction in the maleimide upper ring, wascarried out which resulted in the synthesis of diversely substituted4-hydroxybenzo[ A]pyrrolo[3,4- C]carbazoles.

Studies of 7-hydroxybenzo-4-pyrones
Talanta, 1980Spectral data and rates of hydrolysis in 0.7M potassium hydroxide are reported for a series of nine 7-hydroxybenzo-4-pyrones differing in substitution at positions 2 and 3. The results reveal that 2,3-dimethyl substitution produces a molecule, 7-hydroxy-2,3-dimethylchromone, sufficiently fluorescent and resistant to alkaline hydrolysis to warrant its ...
