  Incorporation of the quinoline-5,8-quinone moiety into polyaza cavities

  摘要：

  Silica gel supported nitric acid treatment of 2,5-dimethoxybenzaldehyde followed by reduction with iron powder provides 3,6-dimethoxy-2-aminobenzaldehyde. Friedlander condensation of this species with a variety of ketones and diketones leads to 5,8-dimethoxyquinoline derivatives which may be oxidized by ceric ammonium nitrate (CAN) and pyridine-2,6-dicarboxylic acid N-oxide (PDANO) to the corresponding quinones. The quinone functionality can be incorporated into larger cavities by a selective stepwise Friedlander approach and the CAN/PDANO oxidation appears to work preferentially for 5,8-dimethoxyquinoline.
