Abstract
The Prins cyclization of homoallyl alcohol with a variety of aldehydes were observed under reflux condition in dichloromethane using both polyaniline supported TsOH PANITsOH and FeCl3PANI FeCl3 as reusable acid catalysts with the formation of 24disubstituted tetrahydropyran ether as single product In case of 4 3 and 2 nitro benzaldehydes the reaction generated acetal of the aldehyde and homoallylic alcohol as single product Additionally both catalysts were investigated for the synthesis of 1 3dioxane in dichloromethane under reflux and at ambient temperatureThe Prins cyclization of 3butene1ol with aromatic aldehydes yielded 24 disubstituted tetrahydropyran ether 4 as single product in dichloromethane using both PANITsOH and PANIFeCL3 as reusable acid catalysts Both catalysts were investigated for the synthesis of 1 3dioxane in dichloromethane
