We report the synthesis of the azaoxoaporphine alkaloidsampangine (4) and a series of ring A analogues and isomers of the marine pyridoacridine alkaloid ascididemin (2). This approach starts from readily available 1-bromo[2,7]naphthyridine (12) or 4-bromobenzo[c][2,7]naphthyridine (5), and the ring A scaffold bearing an ester moiety is introduced by a Suzuki or Negishi cross-coupling reaction.

Benzo[c][2,7]naphthyridines bearing electron-withdrawing substituents (bromo, acetyl) at C-4 undergo regioselective homolytic substitutions at C-5 with nucleophilic 1,3,5-trioxanyl and ethoxycarbonyl radicals under Minisci conditions. Surprisingly, mainly 5,6-dihydro derivatives are formed in these reactions. Rearomatization with manganese dioxide leads to 4,5-disubstituted benzo[c][2,7]naphthyridines, which should be attractive building blocks for the synthesis of pyridoacridine alkaloids. Homolytic methylation at C-5 takes place with methyl radicals generated from acetic acid and acetaldehyde, respectively. (C) 2012 Elsevier Ltd. All rights reserved.

A novel approach to ring A analogues of the marine pyridoacridine alkaloid ascididemin starting from readily available 4-bromobenzo[c][2,7]naphthyridine (10) comprises a high-yield Minisci-type homolytic methoxycarbonylation at C-5, followed by introduction of the ring A scaffold via Suzuki cross-coupling reaction, and a trifluoromethanesulfonic acid-aided Friedel-Crafts-type intramolecular acylation. This protocol allows for the introduction of various electron-rich carbocyclic and heterocyclic ring A substitutes. (C) 2013 Elsevier Ltd. All rights reserved.
