Abstract
C-glycosylflavonoids represent a group of oxygen heterocyclic compounds found widespread in a variety of plants. Synthetic organic chemists are now progressively utilizing C-glycosylflavonoid scaffolds due to their high biological potential. The present review deals with advances in C-glycosylflavonoids research, namely establishing a new updated database of the natural occurrence of Cglycosylflavonoids - one hundred and nine new structures have been reported up to 2011. The structural characterization of some novel C-glycosylflavonoids from various plant species is also discussed. The reported organic synthetic routes along with the biosynthetic aspects of C-glycosylflavonoids are also reviewed. Finally the paper underlines the wide range of C-glycosylflavonoid biological activity. The mentioned topics are detailed in particular chapters and are supported in 187 references.

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
