Abstract
The catalytic intermolecular cyclization of thiophenols with allylic alcohols in the presence of bismuth triflate afforded the corresponding thiochroman derivatives in a one-pot reaction. The Bi(OTf)3-catalyzed reaction was applied to the intermolecular cyclization of diaryl disulfides with 3-methylbut-2-en-1-ol, to produce the corresponding thiochromans.
