Abstract The structure elucidation of several minor phenazine pigments of Pseudomonads is described. 4-Hydroxyphenazine-1,6-dicarboxylic acid dimethyl ester, 2,3-dihydroxyphenazine, 2,3,7-trihydroxyphenazine, 4-hydroxyphenazine-1-carboxylic acid, 2,3-dihydroxyphenazine-1-carboxylic acid, 2,6-dihydroxyphenazine-1-carboxylic acid and 2,3,7-trihydroxyphenazine-1,6-dicarboxylic acid are new phenazine derivatives. The distribution of phenazines in the genus Pseudomonas is investigated.

Flash thermolysis of dimethyl 3-oxatricyclo[3.2.2.02,4]nona-6,8-diene-6,7-dicarboxylate (the oxide of barrellene-2,3-dicarboxylic acid dimethyl ester) (2) at 700 °C gave methyl isocoumarin-7-carboxylate (3) as a major component of the thermolysate. The rearrangement is discussed in terms of sigmatropic shifts in cycloheptatrienes and their norcaradiene tautomers.
