A simple protocol for the synthesis of indane-based spirocyclics has been developed via enynemetathesis, Diels–Alderreaction, and a [2+2+2] cycloaddition as keysteps starting from indane-1,3-dione. The key diene building block was assembled by enynemetathesis. In this sequence, rongalite is used as a green reagent to prepare the sultine intermediate, which is a useful precursor to generate the
