Synthesis of 2‑Sulfenylindenones via One-Pot Tandem Meyer–Schuster Rearrangement and Radical Cyclization of Arylpropynols with Disulfides

A tandem annulation of arylpropynols with disulfides has been developed for the synthesis of 2-sulfenylindenone derivatives. The reaction pathway involves one-pot tandem Meyer–Schuster rearrangement of arylpropynols and successive radical cyclization with disulfides. Various arylpropynols and disulfides with a number of functional groups are compatible in this reaction that affords the corresponding 2-sulfenylindenones in moderate to good yields.
