摘要：

Diastereotopos-differentiation is the key feature of the catalytic C-H amination at the benzylic position of substrate 1. Essentially independent of the functional group X (X = COOMe, PO(OEt)(2), SO2Ph, NO2, CN, OAc), the depicted products 2 are formed with good (dr = 80/20) to excellent (dr > 95/5) diastereoselectivity. The reaction proceeds without racemization and possesses potential for the C-H amination of open-chain substrates.
