Abstract
The chemoselective synthesis of indeno[1,2-b]thiophenes was developed through the annulation of α-enolic dithioesters with ninhydrin under solvent-free conditions. This domino reaction sequence is highlighted by the use of inexpensive FeCl3·6H2O, its operational simplicity, a short reaction time, its functional-group tolerance, and the concomitant formation of two bonds and one thiophene ring.
