Double‐action haloketones: A super silyl group enabled the first highlydiastereoselectiveMukaiyamaaldolreactions of α‐chloro‐ and α‐fluoroketones with a wide range of aldehydes, providing anti‐β‐siloxy‐α‐haloketones. This process is compatible with one‐pot double‐aldol methodology and allows for rapid access to new halogen‐modified polyketide fragments bearing up to four contiguous stereocenters
