A highly stereoselective one-pot procedure to anti-configured thiochromans is described. This reaction functions at room temperature in the presence of catalytic amounts of trifluoroacetic acid. The transformation gives a selective but optional access to highly substituted thiochromans, which have been not attainable until now.
