An efficient approach via catalytic electrophilic thiocarbocyclization of allenes to construct indene-based sulfides with excellent regioselectivities is disclosed. The reactions were carried out at low temperatures by selenide catalysis in the presence of TMSOTf. Not only electrophilic arylthio reagents but also electrophilic alkylthio reagents worked well under these conditions. Furthermore, the
公开了一种通过丙二烯的催化亲电硫代碳环化来构建具有优异区域选择性的茚基硫化物的有效方法。反应在低温下通过硒化物催化在 TMSOTf 存在下进行。在这些条件下,不仅亲电的芳硫基试剂而且亲电的烷硫基试剂都能很好地工作。此外,该方法可应用于丙二烯的分子间叠氮硫基化反应。
