Abstract

We present a flexible and cost-efficient synthetic strategy for the preparation of a new family of phosphoramidite and solid-support reagents that can introduce a broad range of modifications into DNA probes. The key intermediate material 3 is synthesized using the inexpensive and commercially available 3-(tert-butyldimethylsiloxy)glutaric anhydride 1 and can be used as common starting material for the preparation of new labeling reagents.
