Directed β-C(sp.SUP.3.)#H iodination and arylation of ketones
This invention discloses the first example of palladium(II)-catalyzed -C(sp.sup.3)-H iodination or arylation of a wide range of ketones by using a commercially available aminooxyacetic acid auxiliary. This L, X-type directing group overcomes the limitation of the transient directing group approach for -C(sp.sup.3)-H functionalization of ketones. Practical advantages of this method include simple installation of the auxiliary without chromatography, exceptional tolerance of a-functional groups, double bonds and triple bonds and rapid access to diverse sterically hindered quaternary centers.
