 Title    Pseudoverdin, a Compound Related to the Pyoverdin Chromophore from a Pseudomonas aeruginosa Strain Incapable to Produce Pyoverdins [1]  
 Abstract    From a genetically manipulated strain o f Pseudomonas aeruginosa ATCC 15692 (PAO 1 strain) a com pound named pseudoverdin, 3-form ylam ino-6,7-dihydroxycoumarin, was obtained which is related to the typical pyoverdin chromophore and thus allows to shed some light on the biogenesis o f the latter.

 Title    A Convenient Synthesis of the 2-Diinethyl-2H-Chroinene-System  
 Abstract    -pyrano(3,2-c)-l-benzopyrano-5-one(2) and 4H-2,3-dihydro-3-methyl-2-methylene-furan-l-benzopyran-4-one (3), two new coumarin derivatives were synthesised from 4-hydroxycoumarin by treating with 3-chloro-3-methylbut-l-yne and 3-chlorobut-l-yne respec-tively, both reactions progressing via the phase-transfer catalysis.
