Ligand- and catalyst-free intramolecular C-S bond formation: direct access to indalothiochromen- 4-ones

An efficient ligand- and catalyst-free intramolecular -arylation leading to the direct synthesis of indalothiochromen-4-ones from simple dithioesters under mild conditions has been developed. This method is particularly noteworthy given its experimental simplicity, high generality, and good function...

Summary:An efficient ligand- and catalyst-free intramolecular -arylation leading to the direct synthesis of indalothiochromen-4-ones from simple dithioesters under mild conditions has been developed. This method is particularly noteworthy given its experimental simplicity, high generality, and good functional group toleration.
