An MNDO Research on Pseudo-rotation isomers of Intramolecular Mixed Anhydride Formed from N-diisopropylphosphoryl-alanine

By means of MNDO MO calulations, the structures and properties of pseudo-rotation isomers of an pentacoordinate phosphorus intermediate formed from N-phosphoryl-a-alanine were studied. As it truned out that the isomers are hihgly active and have various reactiveties, therefore they may become synthons with multi-activity.
