Synthesis of 2'-deoxy-2',3'-secothymidine t and its dimer tt, where t
he two 2'-deoxy-2',3'-secothymidine t units are connected via a carbam
ate, =3'-NH-CO-O-5', internucleoside linkage has been achieved. These
building blocks were protected in the 5'-position, converted into the
ir phosphoramidites, or attached onto CPG, and then used for ''chimeri
c oligonucleotide'' synthesis.
