Abstract

A series of 4, 8-substituted 1, 5-naphthyridines (1a–1h) have been successfully synthesised by a Suzuki cross-coupling between 4, 8-dibromo-1, 5-naphthyridine (4) and the corresponding boronic acids (2a–2h) in the presence of catalytic palladium acetate in yields of 41.4–75.8% and have ben well characterized. They are thermally robust with high phase transition temperatures (above 186° C). Compounds 1b, 1e and 1f crystallized in the ...
