Witryna1 kwi 2007 · However, only a few mono- and di-substituted 2,7-naphthyridine derivatives have been prepared. Mostly the fuctionalized naphyridine compounds have to be prepared from their chlorides, while the aromatic chlorides are not active enough; their substitution reactions require harsh conditions, such as high temperature and high … Witryna4 lip 2024 · The above-mentioned alkaloids are all 2,7-naphthyridine-4-carboxylic acid derivatives, since in position 4 of the naphyridine moiety, they have an ester, carboxamide or carbonitrile. There are also plenty of 2,7-naphtyridines that are bioactive and have structures that differ from natural products.
