Abstract
This review covers synthetic work carried out in the field of stilbene and oligostilbene chemistry. It includes a brief overview of the methods used for the synthesis of monomeric stilbenoids. The production of oligomeric species by means of enzymatic or microbial conversion is examined in detail. Biomimetic syntheses of stilbene oligomers are then scrutinised. Most of the work is based on the dimerisation of stilbenoid monomers with help of one-electron oxidants or through acid catalysis. Mechanistic interpretations of the oxidative couplings observed by the various groups are proposed and suggest that the outcome of these reaction be guided by the “hard and soft acid and base” (HSAB) principle together with supramolecular interactions between the reacting stilbenoid monomers. Eventually, the few non-biomimetic full syntheses are presented and their strategies analysed.

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
