The article was written by Tran, Kristy; Beutner, Gregory L.; Schmidt, Michael; Janey, Jacob; Chen, Ke; Rosso, Victor; Eastgate, Martin D.. The article contains the following contents:
The development of a diastereoselective nucleoside phosphorylation is described, which produces a single isomer of a complex nucleoside monophosphate prodrug. A stable phosphoramidic acid derivative is coupled to the nucleoside, in a process mediated by HATU and quinine, to deliver the coupled product in high chem. yield and good diastereoselectivity. This unusual process was shown to proceed through a dynamic kinetic resolution of a 1:1 mixture of activated phosphonate ester diastereoisomers. The optimized conditions afforded the product with a combined [S,S(P)] and [S,R(P)] in-process yield of 89% and a ∼ 7:1 [S,S(P):S,R(P)] diastereomeric ratio. Isolation of the major isomer was facilitated by single crystallization from anisole, where the product was obtained in 57% isolated yield, excellent purity (>95%), and a high diastereomeric ratio (>50:1). The experimental process involved the reaction of ((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6Related Products of 56602-33-6)
((1H-Benzo[d][1,2,3]triazol-1-yl)oxy)tris(dimethylamino)phosphonium hexafluorophosphate(V)(cas: 56602-33-6) is used as a reagent for peptide coupling, lactonization, selective esterification, amidation of alfa amino acids without racemization and synthesis of magnolamide for antioxidative activity and catalyst for 9-acridinecaroboxamide derivative. It is also used as a precursor for the synthesis of phenyl esters of amino acids.Related Products of 56602-33-6
