an appropriate bisphosphine ligand have been shown to effectively catalyze the formation of substituted tetrahydropyrans via a sequential olefin migration and Prins-type cyclization. This methodology provides convenient access to a variety of functionalized tetrahydropyrans in excellent diastereoselectivities and good to excellent yields.
Cu(OTf) 2与合适的双膦配体的金属配体配合物已被证明可通过顺序烯烃迁移和 Prins 型环化有效催化取代四氢吡喃的形成。这种方法可以方便地获得各种具有出色非对映选择性和良好收率的官能化四氢吡喃。
