Enantioselective Allylation of Aromatic Amines After in situ Generation of an
Activated Cyclometalated Iridium Catalyst. — The first convenient and highly selective allylic amination with aromatic amines lacking an activation group is reported.
An iridium precatalyst is converted into an active cyclometalated catalyst either in situ
prior to addition of the aromatic amine or with DABCO additive in the presence of
aniline. The reaction occurs with electron-neutral and electron-rich aromatic amine nucleophiles as well as aromatic or aliphatic allylic carbonates. — (SHU, C.; LEITNER,
