Abstract
Activation of imines by hydrogen bonding is a very powerful way of promoting the synthesis of a variety of nitrogencontaining compounds of interest. Such a useful approach typically involves mild reaction conditions, simple experimental operations and metal-free reagents. The present review focuses on the recent development of new organocatalytic methods involving imines and related compounds as substrates in which activation through hydrogen bonding is performed. The different modes of activation are thoroughly illustrated with special emphasis on mechanistic aspects of the reactions and how activation is actually produced.

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
