A variety of (E)‐N‐aryloxindole nitrones were prepared in good to excellent yields by using a copper‐catalyzed coupling reaction of isatin oximes and arylboronic acids under mild conditions. Various arylboronic acids that contain sensitive functional groups were tolerated in the transformation, and detailed studies show that the carbonyl group of the isatin oximes serves as a ligand to control the formation of the (E)‐oxindole nitrones. This method to prepare (E)‐N‐aryloxindole nitrones was easily performed on a gram scale and efficiently used to synthesize estrone‐derived oxindole nitrone in high yield.
An efficient carbonyl group controlled strategy was developed to prepare (E)‐N‐arylisatin ketonitrones in good to excellent yields from the copper‐catalyzed coupling reaction of isatin oximes and arylboronic acids under mild conditions. DCE = 1,2‐dichloroethane.
