RT Journal Article T1 Assembly of Tetrahydroquinolines and 2-Benzazepines by Pd-Catalyzed Cycloadditions Involving the Activation of C(sp3)–H Bonds A1 Vidal Pereira, Xandro A1 Mascareñas Cid, José Luis A1 Gulías Costa, Moisés K1 Hydrocarbons K1 Aromatic compounds K1 Annulations K1 Allenes K1 Cyclization AB Cycloaddition reactions are among the most practical strategies to assemble cyclic products; however, they usually require the presence of reactive functional groups in the reactants. Here, we report a palladium-catalyzed formal (4 + 2) cycloaddition that involves the activation of C(sp3)–H bonds and provides a direct, unconventional entry to tetrahydroquinoline skeletons. The reaction utilizes amidotolyl precursors and allenes as annulation partners, and is catalyzed by Pd(II) precursors in combination with specific N-acetylated amino acid ligands. The reactivity can be extended to ortho-methyl benzylamides, which provide for the assembly of appealing tetrahydro-2-benzazepines in a formal (5 + 2) annulation proces PB American Chemical Society SN 1523-7060 YR 2021 FD 2021 LK http://hdl.handle.net/10347/26594 UL http://hdl.handle.net/10347/26594 LA eng NO Org.
