An Expeditious Synthesis of cis-2-(Aroylmethyl)-4-phenylthiochromans by Iodine-Catalyzed Combination of Thiophenol with Cinnamylidene­acetophenones

Cinnamylideneacetophenones have been found to undergo facile cyclocondensation with thiophenol in dichloromethane under iodine-catalyzed conditions yielding cis -2-(aroylmethyl)-4-phenylthiochromans in very good to excellent yield. The structures of the products have been established from their spectral data as well as X-ray crystallographic studies on one of them.
