A pincer for high selectivity: A mild palladium-catalyzed hydroamination of protected amino-1,3-dienes has been developed. This highly regioselective reaction employs a tridentate PNP pincer ligand and leads to cyclic and homoallylic protected amines in high yields. Substrates with a wide array of amine protecting groups and diene substitution patterns were cyclized to form five- and six-membered heterocycles. PG=protecting group.
