since a stereoisomer with a hydroperoxy or hydroxy group equatorial has not been isolated from the ozonolysis synthesis or from the fenton oxidation of cyclophosphamide ( cp ) , the configuration with c4-oxygen axial which is found in 4-hydroperoxy-cp and both isomers of 4-hydroperoxy-i is probably more stable and may be the configuration of 4-hydroxy compounds formed by the in vivo oxidation of cp , isophosphamide , and trophosphamide ( tp ) .
