The nitration of electron-rich aromatics
Dwyer,Holzapfel
, p. 7843 - 7848 (2007/10/03)
The successful mononitration of a variety of electron-rich aromatic substrates is reported, employing either nitronium tetrafluoroborate or 'claycop' as the nitrating agent. Dinitration of four of the substrates was achieved when employing nitronium tetrafluoroborate. Several of the products have previously been prepared only by indirect methods.
Studies of Chromenes. Part 9. Syntheses of Chromenequinones
Brown, Philip E.,Lewis, Robert A.,Waring, Mark A.
, p. 2979 - 2988 (2007/10/02)
Syntheses of 2,2-dimethylchromene-5,8-quinone, 2,2-dimethylchromene-6,7-quinone, and 6,7-dimethoxy-2,2-dimethylchromene-5,8-quinone are described.Being easily bioreductible to electron-rich chromenes these compounds, and their oxirane derivatives, are of
