NMR and X-ray diffraction studies revealed that, independently of the P-substituent and the relative configuration of the phosphorus atom, 13, 14, 17 and 18 could be characterized by trans-connected hetero rings and the chair conformation of the 1,3,4,2-oxadiazaphosphinane moiety, while the stereochemistry of the connection of the hetero rings in the 1,3,4,2-oxidiazaphosphinanes linearly fused to tetrahydroisoquinoline (15 and 16) was found to be dependent on the P-configuration relative to that of the carbon at the annelation.
