The octahydroquinolines 24 and decahydroacridines were obtained from dimedone. On montmorillonite KSF clay, acridine derivatives 25 were obtained. Reaction of arylidenemalononitriles with cyclic ketones gave 2-amino-3-cyanopyridines 26. Reaction of diphenylamine and dicarboxylic acids or arylacetic acids was catalyzed by zinc chloride to give acridines. Pyrimido[4,5-Z>]quinolines 27 were synthesized. ... [Pg.5]

Observed limitations include partial decarboxylation during ring closure in the synthesis of phenazine-1,9-dicarboxylic acid as well as poor yield and very low reactivity of ketal-protected ketone diphenylamine in the cyclization step of saphenic acid synthesis. The deprotected ketone was cyclized and reduced in one step, affording the desired saphenic acid in satisfactory yields. [Pg.20]
