The invention is directed to processes for synthesizing bicyclic nucleoside antiviral compounds and for synthesizing the intermediates used in the process. The invention is also directed to novel intermediate compounds useful in the process. The anti-viral compounds are useful in the treatment of herpes zoster (i.e., varicella zoster virus, VZV, shingles) and for the prevention of post herpetic neuralgia (PHN) resulting from this viral infection.
该发明涉及合成双环核苷类抗病毒化合物的过程以及用于该过程的中间体的合成。该发明还涉及在该过程中有用的新型中间体化合物。这些抗病毒化合物可用于治疗带状疱疹(即
水痘-带状疱疹病毒,VZV,带状疱疹)并预防由该病毒感染引起的后遗神经痛(PHN)。
