Abstract
Treatment of 1-(2-vinylphenyl)propan-2-ols, which can be easily prepared from 2-bromostyrenes and epoxides, with hydriodic acid in acetonitrile yields the corresponding isochromans (1H-3,4-dihydro-2-benzopyrans). When the above alcohols are treated with iodine in acetonitrile in the presence of sodium hydrogencarbonate, the corresponding 1-iodomethylisochromans are obtained, which can be easily converted into the corresponding 1-alkyl(or aryl)sulfanylmethylisochromans on treatment with sodium thiolates in DMF.
