A novel approach to ring A analogues of the marine pyridoacridine alkaloid ascididemin
摘要:
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.
