Ni-Catalyzed Stereoselective Arylation of Inert C–O bonds at Low Temperatures
摘要:
A Ni-catalyzed arylation of inert C-O bonds that operates at temperatures as low as -40 degrees C is described. Unlike other methods for C-O bond cleavage utilizing organometallic species, this protocol operates at low temperatures, thus allowing the presence of sensitive functional groups with exquisite site-selectivity and stereoselectivity.

A novel palladium‐catalyzed intramolecularfluorooxylation of styrenes has been developed by using NFSI as fluorinating reagent. This reaction provides an efficient way for the synthesis of 2‐aryl‐3‐fluorotetrahydrofuran derivatives.

The copper‐catalyzed intramolecular diastereoselective trifluoromethylcycloetherification of homoallylic alcohols with Togni’s reagent as trifluoromethylating reagent was realized under mild conditions. Various trifluoromethylated tetrahydrofurans were synthesized in moderate to good yields. Moreover, a wide range of common functional groups was tolerated.
