Abstract
4-C-Modified nucleotides and oligonucleotides have been explored extensively recently. The motivations for these investigations drive from the development of new drugs to investigations of complex biological processes. This review covers the common strategies for the synthesis of 4-C-modified nucleosides that have been subsequently incorporated into oligonucleotides. After a brief depiction of two mainly followed routes for the generation of 4-C-modified nucleosides, the synthetic efforts of the modified nucleotides are grouped into those bearing hydrophobic or polar modifications. Subsequently strategies for the incorporation of the respective nucleotides into oligonucleotides by automated DNA synthesis are discussed.

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
