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

with various carbodiimides, has been established by means of chemical correlation and CD spectra. The title rearrangement has been shown to proceed with full retention of configuration at phosphorus. The stereochemistry of the rearrangement under discussion, as well as the different reactivity of various types of phosphorus thioacids towards carbodiimides have been explained in terms of the mechanism
