Synthesis and spectral studies of methyl 10‐(1,3,2‐oxazaphospholidin‐2‐one)undecanoate and methyl 10‐(1,3,2‐diazaphospholidin‐2‐one)undecanoate are reported. These fatty products were obtained in excellent yields when methyl 10‐hydroxyundecanoate was reacted with phosphorus oxychloride, and the resultant intermediate was treated with aminoethanol and ethylenediamine in two different reactions.
