On the basis of chemical transformations and spectroscopic data the cis- and trans-geometry was assigned to the previously reported diastereoisomeric 2-N-phenylamino-2-oxo-4-methyl-1,3,2-dioxaphosphorinans (1). The addition of phenyl azide to cyclic phosphite (3) as well as the reaction of the resulting adduct (4) with carbon disulphide or benzoic acid takes place with overall retention of configuration
