Abstract

An efficient and green method to the synthesis of N‐protected o‐hydroxylphenyl α‐amino‐alkylphosphonic monoesters is described. It consists of the three‐component Mannich‐type reaction of phosphoramides, carbonyl compounds (aldehydes or ketones), and 2‐chlorobenzo[1,3,2] diox‐aphospholes under solvent‐free and catalyst‐free conditions, followed by hydrolysis. © 2008 Wiley Periodicals, Inc.

An efficient procedure is described for the synthesis of N h -Fmoc-O-monobenzyl phosphonotyrosine from the corresponding dibenzyl derivative by monodebenzylation in the presence of sodium iodide. A simple work up procedure removes the by-products and the monobenzylated phosphono product is obtained
