A hydroxymethylated polystyrene resin has been convened to its vinyisuifonylethyl ether (1) by DBU catalyzed addition of the hydmxy groups to divinyl sulfone. The support obtained was used to convert 5-and 6-(tetrahydropyran-2-yloxy)-1,2,3,4-tetrahydroisoquinolines to a set of N-alkylated tetrahydro
During the course of our studies on the abnormal reactlons in poly-tbutylbenzene derlvatlves, 1) we have observed an interesting equilibrium between an N-thiosulfinylanlllne system (2)2) and its cyclic form, 5H-1,2,3dlthlazole (2) , 2 represents the first example of this heterocycllc system,
