Solid phase oligonucleotide synthesis using phospholane intermediates

摘要

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.
