Abstract

Stereocontrolled Mn-mediated addition of alkyl iodides to chiral N-acylhydrazones enables strategic C–C bond constructions at the stereogenic centers of chiral amines. Applying this strategy to quinine suggested complementary synthetic approaches to construct C–C bonds attached at the nitrogen-bearing stereogenic center using multifunctional alkyl iodides 6a–d as radical precursors, or using multifunctional chiral N-acylhydrazones 26a–d as radical ...
