The stereoselective synthesis of the nucleoside phosphoramidite 6 by reaction of the chiral oxazaphospholidine 4 with 5′-DMT-T is reported. The novel phosphoramidite synthon, 6, is stereoselectively converted to 8 by oxidative sulfurization with 1. The oxazaphospholidines, 6 and 8, are a new class of potential nucleosidesynthons for the synthesis of oligonucleotides.
