A simple protocol for the synthesis of indane-based spirocyclics has been developed via enyne metathesis, Diels–Alder reaction, and a [2+2+2] cycloaddition as key steps starting from indane-1,3-dione. The key diene building block was assembled by enyne metathesis. In this sequence, rongalite is used as a green reagent to prepare the sultine intermediate, which is a useful precursor to generate the
已经通过烯炔复分解、Diels-Alder 反应和 [2+2+2] 环加成作为从茚满-1,3-二酮开始的关键步骤开发了合成茚满基螺环化合物的简单方案。关键的二烯构件是通过烯炔复分解组装的。在这个序列中,Rongalite 被用作绿色试剂来制备亚磺酸中间体,这是生成瞬态二烯的有用前体。
