烯丙基醚类的[2.3]Wittig σ迁移重排反应是近几年来新发展的一个有机合成反应。由于此反应具有高度的非对映选择性和立体选择性,它为合成中的碳链延伸、立体选择性反应及不对称合成提供了一个新的方法,因为此反应可通过选择底物的几何构型和取代基得到立体选择性产物。[2.3]Wittig σ迁移重排 The [2.3] Wittig σ migration rearrangement reaction of allyl ethers is an organic synthesis reaction newly developed in recent years. Due to its high degree of diastereoselectivity and stereoselectivity, this reaction provides a new method for the synthesis of carbon chain extension, stereoselective reaction and asymmetric synthesis, because this reaction can be achieved by selecting the substrate geometry Configurations and substituents give stereoselective products.
