Paragraph 0222; 0223; 0224; 0474; 0475; 0476, (2016/10/20)
The invention provides substituted benzoheterocyclic compounds and a preparation method thereof. The compounds have structures shown by formulas I and II. The invention also provides the effects of the compounds shown by formulas I and II in resisting virus, tumor and the like. The invention further provides a medicine composition taking the compounds shown by the formulas I and II as active ingredients, and the anti-virus or anti-tumor effect of the medicine composition. The invention lays a foundation for the future in-depth study and development of the anti-virus or anti-tumor medicine of the compounds.

A short total synthesis of the bacterial coenzyme methoxatin (1) (4,5-dihydro-4,5-dioxo-1H-pyrroloquinoline-2,7,9-tricarboxylic acid) is described.The route involves the two step conversion of 4-acetamido-2-benzyloxybenzaldehyde (5b) into methyl 6-acetamido-4-benzyloxyindole-2-carboxylate (7b) (74percent), followed by regioselective annulation of the third ring (55percent), and debenzylation and oxidation with benzoyl t-butyl nitroxide to give the tricyclic quinone triester (13) (methoxatin triester) (83percent).
Synthesis of the Bacterial Coenzyme Methoxatin

, p. 1372 - 1373 (2007/10/02)
A short synthesis of the bacterial coenzyme methoxatin, based on the thermolysis of the azide (3) to give the indole (4) and the regioselective formation of the pyrroloquinoline (5), is described.
