Crown ethers for the synthesis of heterocycles

Abstract

: Heterocyclic compounds are the largest and most diverse family of organic compounds. Among them, aromatic heterocyclic compounds are the structural motifs found in many biologically active synthetic and natural compounds, agrochemicals, and medicines. Moreover, aromatic heterocyclic compounds are extensively utilized to form 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.
