摘要：
The first highly stereoselective cyclopropanation of diazo Weinreb amides with olefins was accomplished using chiral Ru(II)-Amm-Pheox complex 7a 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).
