Abstract:
Novel amino linker and spacer phosphoramidites were synthesized from methoxyoxalamido (MOX) percursors possessing a secondary hydroxyl, which when phosphitylated endowed stability to the corresponding phosphoramidites. The synthetic strategy is robust, and the chemistry is reactive towards a variety of primary aliphatic diamines and amino alcohols to produce distinctly unique phosphoramidites. The selection of building blocks determines the length and physico-chemical properties of the phosphoramidite tethering arms, and the synthesis can be specifically tailored to suit individual requirement.
