We report on the preparation of novel 1′-homonucleoside derivatives locked in a West conformation by 1′,4′-bridge consisting of annulated benzene or naphthalene ring. The crucial step of the synthesis was Diels–Alder reaction of an appropriate aryne with a suitable furane derivative. Antiviral properties of novel compounds were studied and slight activity against HCV was detected in several compounds.
我们报告了一种制备新型1'-同核苷衍生物的方法,通过1',4'-桥连接的环状苯或萘环将其锁定在West构象中。合成的关键步骤是将适当的芳炔与合适的呋喃衍生物进行Diels-Alder反应。研究了新化合物的抗病毒性能,并在几种化合物中检测到对HCV的轻微活性。
