title: Highly stereoselective cyclopropanation of diazo Weinreb amides catalyzed by chiral Ru(ii)-Amm-Pheox complexes.
abstract: The first highly stereoselective cyclopropanation of diazo Weinreb amides with olefins was accomplished using chiral Ru(ii)-Amm-Pheox complex to give the corresponding chiral cyclopropyl Weinreb amides in high yields (up to 99%) with excellent diastereoselectivities (up to 99 : 1 dr) and enantioselectivities (up to 96% ee).
