The construction of natural product-like, tricyclic compounds is reported. Starting from a d-(−)-ribose-derived dihydrofurane, the tricyclic scaffold is prepared via an intramolecular hetero-Diels−Alder reaction. The reaction proceeds with very high diastereoselectivity through an endo transition state, as established on the basis of X-ray structural analysis of the products. Further modification and
报道了天然产物样三环化合物的构建。从d -(-)-核糖衍生的二氢呋喃开始,通过分子内杂Diels-Alder反应制备三环支架。该反应以很高的非对映选择性通过内在过渡态进行,这是根据产物的X射线结构分析确定的。描述了所得产物的进一步修饰和衍生化。
