Abstract
The vinylsulfonamides 3 of the furan-containing N-benzylamines 2 cycli ze at room temperature to give the delta-sultams 4 with high diastereo selectivity. For the vinylsulfonamides 6 featuring a three atom tether connecting the furan and the dienophile moieties, the equilibrium bet ween 6 and the gamma-sultam 7 is largely shifted towards 7 for N-benzy l substituted 6c in refluxing toluene.
