Molecules containing vicinal all-carbon quaternary stereocenters are found in many secondary metabolites, and they exhibit a variety of biological and pharmacological activities. However, the construction of such a structural motif remains a significant challenge in natural product synthesis. Only in recent years have considerable efforts been made to construct vicinal quaternary stereocenters in a single-step operation. In this review, we focus on the different types of methods that have been successfully used in the total synthesis of natural products. Based on the classified reactions for the simultaneous generation of vicinal all-carbon quaternary stereocenters, the total syntheses of the natural products are discussed, placing emphasis on the diastereoselective preparation of vicinal quaternary carbon centers and the subsequent total syntheses.
含有偕全碳季碳中心的分子存在于许多次级代谢产物中,它们表现出多种生物和药理活性。然而,在天然产物合成中构建这样的结构基序仍然是一个重大挑战。直到最近,人们才做出了相当大的努力,以在单步操作中构建偕季碳立体中心。在这篇综述中,我们重点介绍了已成功应用于天然产物全合成的不同类型的方法。根据同时生成偕全碳季碳立体中心的分类反应,讨论了天然产物的全合成,重点讨论了偕季碳中心的非对映选择性制备以及随后的全合成。
