- Bentrude pointed out7,8 that as a result of the transoid five-to-six-membered ring fusion, one chair and a single twist conformation are accessible for the dioxaphosphorinane ring of such compounds.

- Unpublished NMR data by Bentrude et al. show that the chair conformation is populated predominantly for both R-P-1 (about 90%) and for S-P-1 (about 100%) in DMSO-d6 solution.
