Abstract
The topic of this review is the amide-directed functionalization of strained carbocycles - specifically, unsaturated or saturated three- and four-membered rings. The following approaches are discussed: a) directed carbometallation and hydrometallation of cyclopropenes catalyzed by transition metals; b) directed metal-templated nucleophilic addition reactions; c) directed C-H functionalization, including transition metal-catalyzed C-H-activation reactions; and d) directed radical additions.
Keywords: Small cycles, directing groups, nucleophilic addition, C-H activation, transition metal-catalysis, radical additions.

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
