Abstract

The compounds of the invention include novel linking agents comprising 2-substituted-3-protected-1,3,2-oxazaphosphacycloalkanes and their phosphoramidite precursors. The compounds of the invention further include conjugates of the above linking agents with oligonucleotides and polymer supports. The compounds of the present invention are useful for linking organic moieties, such as fluorescent or chromogenic dyes, to polymer supports and oligonucleotides, particularly single- and double-stranded DNA and RNA fragments.
