A new synthesis of cyclobut-A, a carbocyclic nucleoside analogue of oxetanocin is described. The key step involves a stereoselective intramolecular [2+2] photocycloaddition to provide a trisubstituted cyclobutane derivative with the desired stereochemistry. The nucleoside linkage was established through nucleophilic displacement of an acetate group by adenine.
描述了环丁烷-A(氧杂环丁烷辛的碳环核苷类似物)的新合成。关键步骤涉及立体选择性分子内[2+2]光环加成,以提供具有所需立体化学的三取代环丁烷衍生物。核苷键是通过腺嘌呤亲核置换乙酸基团而建立的。
