The first iridium catalyzed, enantioconvergent amination of allenylic carbonates is reported. This process utilizes various commercially available carbamates and sulfonamides to generate allenylic amines including commonly employed protected groups (Boc, Fmoc, Cbz, Ts, Ns) in 62–82 % yield and 87–98 % ee. The products generated through this scalable procedure serve as effective linchpins for the rapid
