Abstract
Heterocyclic compounds are the largest and most diverse family of organic compounds. Among them, aromatic heterocyclic compounds are the structural motifs found in a great number of biologically active synthetic and natural compounds, agrochemicals, and medicines. Moreover, aromatic heterocyclic compounds are extensively utilized for the formation of dyes and polymeric materials of great importance. In organic synthesis, there are several reports on the uses of aromatic heterocyclic compounds as intermediates. In this review article, we have focused on the synthesis of heterocycles using crown ethers.
Keywords: Crown ethers, heterocycles, synthesis, nitrogen, oxygen, sulfur.

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
