Macrocyclic lactones can be prepared from lactams and hydroxyacid derivatives via an efficient 3‐ or 4‐atom iterative ringexpansion protocol. The products can also be expanded using amino acid‐based linear fragments, meaning that macrocycles with precise sequences of hydroxy‐ and amino acids can be assembled in high yields by “growing” them from smaller rings, using a simple procedure in which high
