| Abstract: | The H‐phosphonate bioconjugates of bile acids, conjugated with various alcohols and nucleosides, were obtained in one pot by a tandem transesterification with diphenyl phosphite (DPP). The synthesis of cholic acid derived phosphoramide from the corresponding H‐phosphonate was also demonstrated. The structures of these novel conjugates were confirmed on the basis of IR,31P NMR, 1H NMR, and mass spectra. The synthesized bile acid conjugates were mixtures of diastereoisomers due to the chirality of the phosphorus. © 2008 Wiley Periodicals, Inc.
