Novel aryne Diels-Alder reactions with functionalized acyclic dienes are reported. These give useful cis-substituted dihydronaphthalene building blocks in good yield which are not easily accessible via other means, as demonstrated in the synthesis of sertraline. The first asymmetric aryne cycloaddition with an acyclic diene is also reported, giving excellent diastereoselectivities with Oppolzer's sultam
报道了与官能化无环二烯的新型芳炔 Diels-Alder 反应。如舍曲林的合成所示,这些以良好的收率提供了有用的顺式取代的二氢萘结构单元,其不易通过其他方式获得。还报道了第一个与无环二烯的不对称芳炔环加成反应,以 Oppolzer 的 sultam 作为手性助剂提供了出色的非对映选择性。
