Non‐Dilute Synthesis of Macrodiolides and Macrotetrolides Enabled by Confinement Catalysis

open access: yesAngewandte Chemie, EarlyView.
Confinement catalysis within a hexameric resorcin[4]arene capsule enables macrolactonization under non‐dilute conditions (up to 0.1 M), overcoming the limitations of high‐dilution protocols (0.1–10 mM). This strategy provides direct access to 18–32‐membered macrodiolides and 26–32‐membered macrotetrolides in one pot and unlocks previously inaccessible ...
