title: Indium(III) chloride catalyzed highly diastereoselective domino synthesis of indenodithiepines and indenodithiocines.
abstract: An atom-economical diastereoselective synthesis of indenodithiepines and indenodithiocines has been developed via a domino reaction of propargylic alcohols and dithioacetals in the presence of InCl3 as a catalyst. A range of functionalized dithiepines and dithiocines, fused to the indene ring, were obtained in good to excellent yields under mild conditions.
