- A short synthesis of 9-fluoroellipticine from 5-fluoroindole?
-
A synthesis of 9-fluoroellipticine (1c) from 5-fluoroindole (6) is described that features the regioselective lithiation of 5-fluoro-1-(phenylsulfonyl)indole (7) followed by chemoselective acylation of 3,4-pyridinedicarboxylic anhydride. Subsequent cyclization of keto acid 9 to keto lactam 10 with acetic anhydride and sequential treatment of 10 with methyllithium and sodium borohydride affords 9-fluoroellipticine.

- A novel method for the nitration of simple aromatic compounds
-
Simple aromatic compounds such as benzene, alkylbenzenes, halogenobenzenes, and some disubstituted benzenes are nitrated in excellent yields with high regioselectivity under mild conditions using zeolite β as a catalyst and a stoichiometric quantity of nitric acid and acetic anhydride. The zeolite can be recycled, and the only byproduct is acetic acid, which can be separated easily from the nitration product by distillation; the process is inexpensive and represents an attractive method for the clean synthesis of a range of nitroaromatic compounds. For example, nitration of toluene gives a quantitative yield of mononitrotoluenes, of which 79% is 4-nitrotoluene; fluorobenzene gives a quantitative yield of mononitro compounds, of which 94% is 4-nitrofluorobenzene; and 2-fluorotoluene gives a 96% yield of mononitro products, of which 90% is the 5-nitro isomer and 10% is the 4-nitro isomer.
