PHOSPHORUS SULFUR AND SILICON AND THE RELATED ELEMENTS
4-Substituted-4-triphenylphosphonio-5(4H)-oxazolones, when reacted with hyd
rogen iodide in methylene chloride at room temperature, undergo hydro-de-ph
osphoniation to 5(4H)-oxazolonium salts, which react with methanol and trie
thylamine to give the corresponding N-acyl alpha-amino acid methyl esters.
The possible mechanisms of hydro-de-phosphoniation is discussed.
