 note = {This paper describes the reaction mechanisms for the stereoselective synthesis of deoxyribnucleoside 3′-cyclic phosphoramidites as well as dinucleoside phosphite derivatives by the oxazaphospholidine approach. All the key reactions in the present approach were analyzed on the basis of ab initio molecular orbital calculations for the model compounds at the HF/6-31G* level.},
