oxazaphospholes were prepared from L-prolinol and phenylphosphonic or thiophosphonic dichloride and their absolute configurations were determined based on the interpretation of NMR spectra. The base-catalyzed methanolysis of those compounds was found to proceed by exclusive PO bond cleavage with complete inversion of configuration.
