Asymmetric synthesis of 6,7-dimethoxy-1-vinyltetrahydroisoquinolines through Pd-catalyzed intramolecular allylic amination of 3-(amidoethylphenyl)prop-2-enyl carbonates was studied, using a library of fine-tunable monodentate phosphoramidite ligands. Unde

A simple and effective one-pot, two-step intramolecular aryl C-N and C-O bond forming process for the preparation of a wide range of benzo-fused heterocyclic scaffolds using iron and copper catalysis is described. Activated aryl rings were subjected to a highly regioselective, iron(III) triflimide-catalyzed iodination, followed by a copper(I)-catalyzed intramolecular N-or O-arylation step leading to indolines, dihydrobenzofurans, and six-membered analogues. The general applicability and functional group tolerance of this method were exemplified by the total synthesis of the neolignan natural product, (+)-obtusafuran. DFT calculations using Fukui functions were also performed, providing a molecular orbital rationale for the highly regioselective arene iodination process.
