## Abstract **Three contiguous stereocenters** can be established with remarkable diastereoselectivity in a double Reformatsky sequence. Densely functionalized γ‐butyrolactones were assembled rapidly by this approach, in which a ketone is used as the terminal electrophile (see scheme). Secondary tr
