Copper-Catalyzed Intermolecular Cyanotrifluoromethylation of Alkenes
摘要:
A novel and highly practical reaction for the copper-catalyzed intermolecular cyanotrifluoromethylation of alkenes is presented here. This methodology provides a general and straightforward way to synthesize a variety of useful CF3-containing nitriles, which can be used for further preparation of pharmaceutically and agrochemically important compounds in synthetic organic chemistry.

A copper-catalyzedintermolecular cyanotrifluoromethylation of alkenes has been developed, in which the less reactive Togni reagent 2 was used as a CF3 source and TMSCN was employed as a cyano source. Both activated and unactivated alkenes were suitable for this transformation to give CF3-containing organonitriles under mild conditions.

Trifluoromethyl substitution is notably popular in pharmaceuticals and agrochemicals; however, trifluoromethylated compounds normally rely on the use of cost-prohibitive or gaseous trifluoromethylating reagents, which diminishes the general applicability of these methods. Herein an efficient trifluoromethylationreagent trifluoromethylsulfonyl–pyridinium salt (TFSP) was reported, which can be readily

aminoglutethimide. Four new fluorinatedderivatives (5), (6), (8) and (9) have been prepared, in which fluorine substituents have been introduced into the phenyl ring and the ethyl side chain. 4-Fluoroglutethimide (5) and 3-trifluoroglutethimide (6) were synthesised from the corresponding fluorophenylacetonitriles (10) and (14) via sequential monoethylation, Michael addition to methyl propenoate and cyclisation.
