Described herein is a chiral magnesium bisphosphate-catalyzed asymmetric double C(sp3)-H bond functionalization triggered by a sequential hydride shift/cyclization process. This reaction consists of stereoselective domino C(sp3)-H bond functionalization: (1) a highly enantio- and diastereoselective C(sp3)-H bond functionalization by chiral magnesium bisphosphate (first [1,5]-hydride shift), and (2) a highly diastereoselective C(sp3)-H bond functionalization by an achiral catalyst (Yb(OTf)3, second [1,5]-hydride shift).

The first example of copper-catalyzed intramolecular N-arylation of hydroxamic acid derivatives is presented. Based on this transformation a new method for the synthesis of N-alkoxyindol-2-ones from 2-(2-bromoaryl) acetylhydroxamates has been developed. T
