A transformation of fluxional into configurationally stable axially chiral N-arylpyrroles was achieved with a highly atroposelective electrophilic aromatic substitution catalyzed by a chiral-at-metal rhodium Lewis acid. Specifically, N-arylpyrroles were alkylated with N-acryloyl-1H-pyrazole electrophiles in up to 93 % yield and with up to >99.5 % ee, and follow-up conversions reveal the synthetic utility of this new method. DFT calculations elucidate the origins of the observed excellent atroposelectivity.

This paper reports a metal-free and external oxidant-free electrochemical method for the C-3 amination of 2H-indazoles. The protocol employs commercially available azoles and aliphatic amines as amination reagents and has a broad substrate scope, providing the corresponding C3-amination products in high yields at room temperature. Mechanistic studies indicate that an oxidative addition/elimination sequence is involved under electrochemical conditions.
