Polymer-bound diazonium salts for the synthesis of diazoacetic esters

摘要

Starting from Merrifield resin, various polymer-bound diazonium salts were prepared. Upon treatment with amino acid esters, resulting the appropriate triazenes, the corresponding diazoacetic esters were formed by basic cleavage. Scope and limitation of this transformation were investigated. (c) 2005 Elsevier Ltd. All rights reserved.
