Synthesis and Structural Characterization of the Two Epimeric O-Cholesteryl-O-phenyl-N-phenylphosphoramidates.

-The title O-cholesterylphosphoramidate (III) is synthesized as intermediate for the stereoselective synthesis of organophosphates and phosphorothioates. Single crystal X-ray diffraction discerned four independent P-epimeric phosphoramidates for (III). -(CEA-OLIVARES, RAYMUNDO; LOPEZ-CARDOSO, MARCELA;

A new anionic phosphorothioate ligand that incorporates the bioactive cholesteryl group was obtained (2), Na(RRЈP(S)O; R, O-phenyl; RЈ, O-cholesteryl) from the phenylphosphoramidate (1) and NaH in dioxane. In order to test the coordination ability of 2, two organoarsenic derivatives were prepared, O
