Here we report a copper‐catalyzed asymmetric propargylic substitution reaction to prepare tetrasubstituted β‐amino‐β‐ethynyl alcohols in high yields and with enantiomeric ratio ( er ) up to 94:6. This transformation generates tetrasubstituted tertiary carbons by utilizing stable cyclic carbonates and amines as substrates, economical copper catalysts, and easily accessible ligands.
