The Preparation of Merrifield‐Resins Through Total Esterification With Cesium Salts

Abstract

Abstract The reaction of chloromethylated polystyrene‐ co ‐1%‐divinylbenzene resin with the cesium salts of N‐protected amino acids proceeds fast and without side reactions to give N‐protected amino acyl resin esters free of quaternary ammonium sites or reactive chloride.
