The invention relates to a process for the asymmetric synthesis of (R)-4-propyldihydrofuran-2(3H)-one starting with trans-2-hexen-l-al and nitromethane, wherein the stereocentre is generated for the first time by an organocatalytic method, which is therefore highly economical and industrially scalable, and has a very low environmental impact (Formula I).
