A catalytic amount of acids catalyzed reaction of α,β-unsaturated aldehydes with arenethiols in 1,2-dichloroethane brought about intermolecular cycloaddition to give the corresponding 4-thioaryl-2,3,4-trihydro-1-benzothiopyrans (thiochromans) in good to e

The thio-Claisen rearrangement of isomeric 3- and 1-methylallyl phenyl sulfides was investigated.It is demonstrated that the thio-Claisen rearrangement of the 3-methyl isomer is preceded by its thioallyl rearrangement to the 1-methyl isomer.The latter undergoes thio-Claisen rearrangement to o-(3-methylallyl)thiophenol, which is cyclized to 2-ethyl-2,3-dihydrobenzothiophene and 2-methylthiochroman under the reaction conditions.
