Indium triflate catalysed tandem allylation–intramolecular hydroalkoxylation was efficiently carried out by using 1 mol-% of the catalyst under mild conditions to afford the dihydrobenzopyran ring system (chroman-type structure) in good yields. Kinetic, mechanistic and theoretical studies are also presented.
通过在温和条件下使用 1 mol% 的催化剂,三氟甲磺酸铟催化的串联烯丙基化 - 分子内加氢烷氧基化有效地进行,以良好的收率提供二氢苯并吡喃环系统(色满型结构)。还介绍了动力学、机械和理论研究。
