摘要:
AbstractNew conjugates of antiviral nucleoside Ribavirin (=1‐(β‐D‐ribofuranosyl)‐1H‐1,2,4‐triazole‐3‐carboxamide; 1) with 1,2‐ and 1,3‐diacyl glycerophosphates have been synthesized by the phosphoramidite method. A combination of 2′,3′‐phenylboronate protecting group for the sugar moiety of the ribonucleoside 1 and 2‐cyanoethyl protection for the phosphate fragment ensured the preparation of the desired compounds with reasonable yields via a small number of synthetic steps.
