note
-
The chloro analogue of 20a was reduced with promising ee (catalyst 5-Ts: 66% yield, 91% ee; catalyst 5-Nps: 56% yield, 86% ee), but the amine displacement was not attempted.

note
-
The copper-catalyzed animations give lower yields with larger n-alkylamines; for example, N,N-dimethylethylenediamine afforded 30% of the displacement product under the usual conditions.
