Highly Regio-, Diastereo-, and Enantioselective Synthesis of Tetrahydroazepines and Benzo[b]oxepines via Palladium-Catalyzed [4+3] Cycloaddition Reactions.
Angewandte Chemie (International ed. in English)
A novel Pd(0)-catalyzed asymmetric [4+3] annulation reaction of two readily accessible starting materials has been developed for building seven-membered heterocyclic architectures. The potential [3+2] side pathway could be suppressed though fine tuning of the conditions. A broad scope of cycloaddition donors and acceptors participated in the transformation with excellent chemo-, regio-, diastereo- and enantioselectivtities, leading to valuable tetrahydroazepines and benzo[b]oxepines.

- Palladium-Catalyzed Decarboxylative Asymmetric Allylic Alkylation of Dihydroquinolinones ORGANIC LETTERS 2019; 21 (6): 1784–88
Palladium-Catalyzed Decarboxylative Asymmetric Allylic Alkylation of Dihydroquinolinones.
A palladium-catalyzed decarboxylative asymmetric allylic alkylation (Pd-DAAA) of benzo-fused and non-benzo-fused delta-valerolactams is disclosed. This methodology gives access to chiral lactams bearing C3-quaternary stereocenters, which are central to many natural products and biologically active compounds. The reaction proceeds via palladium-catalyzed ionization of an allyl ester, followed by carbon dioxide extrusion and recombination of the electrophilic Pd-pi-allyl complex with the in situ generated lactam enolate. This final step converts racemic allylic ester starting materials into enantiomerically enriched substituted lactams with high yield and enantiomeric excess.
