Thirteen nucleoside 5′-triphosphates (NTPs) and their β,γ-bridging oxygen-modified analogs (β,γ-CX2-NTPs, X = H, F, Cl, and Br) have been efficiently synthesized from nucleoside 5′-phosphoropiperidates with 4,5-dicyanoimidazole as the activator. A high-yielding and chromatography-free protocol for the preparation of both natural and base-modified nucleoside 5′-phosphoropiperidates from the corresponding
十三核苷5'-三磷酸(的NTPs)及其β,γ桥接氧改性的类似物(β,γ-CX 2个-NTPs,X = H,F,Cl和Br)已经被有效地从合成核苷5'-以4,5-二氰基咪唑为活化剂的磷酸哌酯。还开发了用于从相应的核苷5'-磷酸制备天然和碱基修饰的核苷5'-磷酸哌啶盐的高产率且无色谱的方案。
