synthesized as potential precursors to chiral phosphite triesters. Oxazaphosphorinanes 10 and 14 derived from cholesterol and camphor respectively were obtained as stable compounds. They led to rearrangement products in the acidic conditions required for coupling. Then, oxazaphosphorinane 22 derived from D-xylose was synthesized, and led to the diastereoselectivesynthesis of a T-T phosphorothioate
