<i>N</i>-Boc-<scp>l</scp>-Valine-Connected Amidomonophosphane Rhodium(I) Catalyst for Asymmetric Arylation of <i>N-</i>Tosylarylimines with Arylboroxines
A catalytic asymmetricarylation of sterically tuned imines with arylboroxines was developed by using N-Boc-l-valine-connected amidomonophosphane rhodium(I) catalyst in n-PrOH. The TMS group used for the steric tuning of imines is convertible to other functionalities that are applicable as a key foothold for the carbon-carbon bond-forming coupling reactions.
