A new and convenient method for the acylation of amino acids in the presence of a modified zeolite: Ersorb (R)
Reaction of free amino acids with acid chlorides in dioxane in the presence of a modified zeolite-type mineral Ersorb-4 results in the formation of the appropriate N-acyl derivatives. High yields were obtained with aryl chlorides. poorer with aliphatic ones. (C) 2002 Elsevier Science B.V. All rights reserved.
