Triflic-acid-catalyzed tandem allylic substitution–cyclization reaction of alcohols with thiophenols—facile access to polysubstituted thiochromans

Triflic-acid-catalyzed tandem allylic substitution–cyclization reaction of alcohols with thiophenols—facile access to polysubstituted thiochromans

Hitherto inaccessible multisubstituted thiochroman derivatives were constructed via the one-pot reaction of thiophenols with allylic alcohols catalyzed by 0.2 equiv triflic acid under metal-free conditions. A variety of thiochroman derivatives can be obtained by this straightforward protocol that al...
