BENZINDOLES. 21. NITRATION OF 3-FORMYL- AND 3-FORMYLBENZINDOLES
It was established that products of monosubstitution of 4-nitro- and 7-nitro-3-formylbenzindoles and products of disubstitution of 4,8-dinitro- and 7,8-dinitro-3-formylbenzindoles are formed in low yields in the nitration of 3-formylbenzindole with sodium nitrate in concentrated sulfuric acid.Similar nitration of 3-formylbenzindole leads to 9-nitro- and 5,6-dinitro-3-formylbenzindoles.The 3-formylnitrobenzindoles obtained were converted to nitrovinyl derivatives by condensation with nitromethane.

The synthesis and evaluation of benzannelated-azatoxins: The benzazatoxins
The synthesis and evaluation of azatoxin congeners possessing annealed aromatic frameworks are described. The compounds were evaluated for their abilities to affect topoisomerase II inhibition through the stabilization of 'cleavable complex' and for the inhibition of tubulin polymerization using purified bovine brain tubulin.
