A novel reagent for the chemical phosphorylation of oligonucleotides

A novel phosphoramidite reagent was developed to convert terminal hydroxyl groups of oligonucleotides into phosphate monoesters. The reagent's appearance as a solid foam is advantageous for its manipulation and handling in solid phase synthesis and improves its thermal stability.
