Abstract
The use of calixarenes in asymmetric catalysis was described. The current progress of asymmetric catalysts based on calixarene scaffold for the enantioselective reactions including allylation, alkylation, addition of diethylzinc to benzaldehyde, Micheal-type addition, aldol reaction, hydrogenation, Friedal Crafts reaction, epoxidation, hydroformylation, and Biginelli reaction was illustrated. In these cases, calixarenes were used as organocatalysts or ligands in metal-catalyzed asymmetric reactions.

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
