The development of a flow chemistry process for asymmetric propargylation using allene gas as a reagent is reported. The connected continuousprocess of allene dissolution, lithiation, Li‐Zn transmetallation, and asymmetric propargylation provides homopropargyl β‐amino alcohol 1 with high regio‐ and diastereoselectivity in high yield. This flowprocess enables practical use of an unstable allenyllithium
