Graphical Abstract
An enantioselective copper-catalyzed intramolecular hydroamination reaction can be used jointly with the Suzuki–Miyaura cross-coupling to yield a diverse array of α-arylpyrrolidine scaffolds that contain pharmaceutically relevant heteroarenes with excellent enantiomeric purity under mild conditions. Furthermore, this intramolecular hydroamination strategy is applicable to the asymmetric syntheses of six- to nine-membered benzo-fused nitrogen heterocycles.
Abstract
Herein, we report a practical two-step synthetic route to α-arylpyrrolidines through Suzuki–Miyaura cross-coupling and enantioselective copper-catalyzed intramolecular hydroamination reactions. The excellent stereoselectivity and broad scope for the transformation of substrates with pharmaceutically relevant heteroarenes render this method a practical and versatile approach for pyrrolidine synthesis. Additionally, this intramolecular hydroamination strategy facilitates the asymmetric synthesis of tetrahydroisoquinolines and medium-ring dibenzo-fused nitrogen heterocycles.

- 27Although (R,R)-Ph-BPE provided the best results in Table 1, (S)-DTBM-SEGPHOS was chosen as the ligand to examine the scope of α-arylpyrrolidines because of cost, availability, and stability.
- 28It is currently unclear whether the erosion of selectivity is due to epimerization of the alkylcopper species before the C−N bond formation. For mechanistic discussions on enantioselective hydrocupration and subsequent epimerization relevant to the hydroboration of alkenes, see: Y. Xi, J. F. Hartwig, J. Am. Chem. Soc. 2017, 139, 12758–12772.

- 31(R,R)-Ph-BPE and DMMS replaced (S)-DTBM-SEGPHOS and DEMS. However, under our standard hydroamination conditions (footnote [b], Table 2), formation of 2-phenylpiperidine 5 was not detected from 4 (footnote [b], Scheme 1) while 2-phenylpyrrolidine 2 a was isolated in 83 % yield from 1 ac.
