Abstract
The Nicholas reaction involves the treatment of a cobalt carbonyl-stabilized propargylic cation with a variety of nucleophiles to form a new carbon-carbon or carbon-heteroatom bond. Several features of this reaction make it especially well suited for applications in natural product synthesis, in particular when cyclic and polycyclic target molecules are involved. This review summarizes the results in this area from the last ten years, including approaches towards terpenes, alkaloids and marine natural products.
Keywords: Alkaloid, cobalt alkyne complex, marine polyether, natural product synthesis, Nicholas reaction, terpene

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
