) phosphite was used as a phosphonylatin E reaEent for the preparation of nucleoside 3'-H-phosphonate units. The use of a new couplin E reaEent, 1,3-dimethyl-2-chloro-imidazolinium chloride (DMCI) for the internucleotidic H-phosphonate bond formation via the H-phosphonate approach is also discussed in detail.
