The 1,3-diamine motif appears in numerous complex molecules, yet there are few methods for the stereoselective construction of this moiety. Herein, we demonstrate a stereocontrolled synthesis of 1,3-diamines, which bear up to three contiguous stereogenic centers, through benzylic ring-opening of aziridines with 2-azaallyl anion nucleophiles. Reactions proceed efficiently (yield up to 95%), diastereoselectively (dr up to >20:1), site selectively, and enantiospecifically to deliver products with differentiated amino groups.

This study demonstrates a stereocontrolled synthesis of 1,3-diamines through benzylic ring-opening of aziridines with 2-azaallyl anion nucleophiles, enabling efficient, diastereoselective, site selective, and enantiospecific delivery of differentiate
