Recent Advances in the Trifluoromethylation Reactions of Isonitriles To Construct CF 3 -Substituted N-Heterocycles

Due to the increasing need for fluorine-containing drugs, the synthesis of organofluorine scaffolds has become a highly researched area of synthetic organic chemistry. The introduction of the trifluoromethyl group into the structure of an organic molecule has considerable potential and several advantages concerning the characteristics of the fluorinated pharmaceuticals. The incorporation of a CF3 group at multiple bonds containing a nitrogen heteroatom is a relatively new field and currently it is an expanding area of synthetic chemistry. This short review summarizes, for the first time, recent developments in trifluoromethylation reactions of isonitriles.1 Introduction2 Trifluoromethylation Reactions of Isonitriles2.1 Synthesis of Trifluoromethylated Phenanthridine Derivatives 2.2 Synthesis of Trifluoromethylated Quinoline Derivatives2.3 Synthesis of Trifluoromethylated Isoquinoline Derivatives2.4 Synthesis of Trifluoromethylated Indole Derivatives2.5 Synthesis of Trifluoromethylated Pyridine Derivatives3 Summary and Outlook
