 Title    Synthesis of Substituted Phenazines from Benzofurazanoxid and Hydroquinones [1]  
 Abstract    The sterical course of the formation of substituted phenazines from benzofurazanoxid and hydroquinone derivatives was investigated. The additional functional group of the hydroquinone determines the substitution pattern and the product ratio of the phenazines formed.

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

 Title    Derivate des 1.3-BenzdioxoIs, 52 [1] Darstellung und Reaktionen von 1.3-Dioxolo[4.5-b]phenazinen Derivatives of 1,3-Benzdioxoles, 52 [1] Preparation and Reactions of l,3-Dioxolo[4,5-b]phenazines  
 Abstract    We describe the preparation of the l,3-dioxolo[4,5-b]phenazines 4 a —p form ed by ferric chloride oxidation o f the corresponding 2,2'-diam inodiphenylam ines. They are obtained by con­ densing the o-nitrohalogenbenzenes l a —g with o-nitroanilines 2 a —i and reduction o f the result­ ing 2,2'-dinitrodiphenylam ines 3 a —p with H 2/Pd.

 Title    Phenazine and Phenoxazinone Biosynthesis in Brevibacterium iodinum  
 Abstract    The source o f nitrogen in the phenazine, iodinin 5, and in 2-aminophenoxazinone 7 in Brevi­ bacterium iodinum cultures is shown to be primarily from the amide nitrogen of glutamine in ex­ periments with (S)-[C 015N H 2]glutamine, [15N]ammonium sulphate, and (S)-[15N]glutamic acid. The biosynthesis of 5 and 7 is closely related; biosynthesis o f 7 like that o f 5 diverts from the shi-kimic acid pathway at a stage prior to anthranilic acid 8.

 Title    Die Bildung hydroxylierter Phenazine durch Pseudomonas fluorescens Y4 bei Be2+-Zusatz zum Kulturmedium -ein Abwehrmechanismus? [ 1 ] The Form ation of Hydroxylated Phenazines by Pseudomonas fluorescens Y4 upon Addition of Be2 to the Culture Medium -a Defense Mechanism?  
 Abstract    Pseudomonas fluorescens Y4 grown in an iron deficient medium produces increased am ounts o f 2,9-di-and 2,3,9-trihydroxyphenazine-l-carboxylic acid when Be2+ is added to the culture. The significance o f the formation o f these com pounds is discussed.

 Title    Further Observations on the Source of Nitrogen in Phenazine Biosynthesis  
 Abstract    It is concluded from experiments with (S)-[C015NH2]glutamine and [15N]ammonium sulphate that the biosynthesis of iodinin (1), in Brevibacterium iodinum, and of phenazine-1-carboxylic acid (7), in Pseudomonas aureofaciens, is primarily from a single nitrogen source (glutamine) and that
