Highly Functional Group Compatible Rh-Catalyzed Addition of Arylboroxines to Activated <i>N</i>-<i>tert</i>-Butanesulfinyl Ketimines

Abstract

The rhodium-catalyzed addition of readily accessible arylboroxines to N-tert-butanesulfinyl ketimines derived from oxetan-3-one, N-Boc-azetidin-3-one, and isatins proceeds in high yields with excellent functional group compatibility. Moreover, high diastereoselectivities are observed for the additions to the N-sulfinyl ketimines derived from isatins.
