Abstract
Methods and compounds are provided for solid phase synthesis of oligonucleotides and related polymers by condensing protected monomer-O- 1,3,2-dichalcogen-substituted-phospholane! synthons in the presence of a catalytic base. Compounds of the invention include 2-N-substituted-1,3,2-dichalcogen-substituted-phospholane precursors of the above synthons, the protected monomer-O- 1,3,2-dichalcogen-substituted-phospholane! synthons, and P-chiral oligonucleotides and related P-chiral polymers.
