Abstract
The siderophores produced by the so-called fluorescent members of the bacterial genus Pseudomonas called pyoverdins are chromopeptides with complex structures. Their peptidic part - linear or partially cyclic - comprises unusual and partially modified amino acids. So far about fifty different pyoverdines have been encountered. A fast establishing at least of their gross structure is of importance for the identification of strains in medicine, agriculture and in waste degradation. Mass spectrometric techniques have become a potent tool in this respect. Results which have been obtained by the various techniques will be reviewed.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
