Phosphoromorpholidate

WebMay 24, 1985 · The bifunctional phosphorylating reagent O,O-bis [1-benzotriazolyl]phosphoromorpholidate was used to introduce a 5'-O-triphosphate and a 3'-O-diphosphate function in a partially protected riboguanosine. In the general phosphoromorpholidate method introduced by the Khorana group, 2–3 molar equivalents of sugar phosphomonoesters were used to react with the activated nucleotide in anhydrous pyridine over 3–5 days at rt. The yields of the prepared NDP–sugars were in between 65% and 70%.
