Abstract
Abstract Treatment of an aldehyde and furan with N -sulfinyl- p -toluenesulfonamide/zinc chloride leads to the formation of furyl sulfonamides via an in situ generated N -tosyl imine intermediate. In one case, a novel 4-tosylamino-5,6-dihydro-4 H -3-oxa-benz[ e ]azulene was obtained by intramolecular aromatic substitution of the activated imine at the 3-position of the furan ring.
