functionalized γ-lactones has been developed involving Sakurai exo-cyclization/rearrangement of 3,3-bis(silyl) enolesters with a tethered acetal. While the steric and electronic effects of geminal bis(silane) favor the desired Sakurai pathway, the methoxy species formed in the deprotection step also facilitates both cyclization and rearrangement. The synthetic value of this approach has been demonstrated by efficiently

This manuscript describes our studies of the class of natural products known as the rubellins, culminating in the totalsynthesis of (+)-rubellin C. These anthraquinone-based natural products contain a variety of stereochemical and architectural motifs, including a 6-5-6-fused ring system, 5 stereogenic centers, and a central quaternary center. Herein, we report our development of a strategy to target
这份手稿描述了我们对称为 rubellins 的天然产物类别的研究,最终导致 (+)-rubellin C 的全合成。这些基于蒽醌的天然产物包含各种立体化学和结构图案,包括 6-5- 6个稠环系统,5个立体中心和一个中央四元中心。在这里,我们报告了我们针对立体化学致密核心和蒽醌核的策略的开发,包括双功能烯丙基硼和三氟甲磺酸乙烯酯试剂、蒽醌苄基金属化策略和后期蒽醌引入策略等方法。我们的研究最终以成功的途径获得高度功能化的蒽醌基天然产物支架和 (+)-rubellin C 的立体选择性全合成。

A general and regiospecific method for the preparation of quinizarins involves the cycloaddition of electron-rich dienes. Advantageous syntheses of several natural products, 2-methylquinizarin, islandicin, digitopurpone, erythroglaucin, 5-0-methylislandicin and 8-0-methyl-digitopurpone illustrate this procedure. A structure attributed to ventinone B is incorrect and 1,4,8-trihydroxy-6-methylanthraquinone
