General description

p-Toluenesulfonamide undergoes FeCl3-catalyzed direct substitution reaction with benzylic and allylic alcohols.It is employed as nucleophile in tetrabutylammonium fluoride (TBAF) catalyzed vinyl aziridine opening reaction.

Application

p-Toluenesulfonamide was used to prepare the precursor required for synthesis of ethyl 6-phenyl-1-tosyl-1,2,5,6-tetrahydropyridine-3-carboxylate.
