Polystyrene-supported TBD (PS-TBD) catalyzes the ring-opening of N-tosylaziridines with silylated nucleophiles to give the corresponding products in high yields. PS-TBD was easily recovered and reused without significant loss of catalytic activity.

Abstract The ringopening of N-tosylaziridines with silylatednucleophiles catalyzed by 1,5,7-triazabicyclo[4,4,0]dec-5-ene (TBD) afforded the corresponding β-functionalized sulfonamides in excellent yields under mild reaction conditions. GRAPHICAL ABSTRACT

A mild and efficient procedure was developed for the regioselective ring‐opening nucleophilic addition reactions of aziridines viavisiblelightphotoredoxcatalysis, that provides a practical synthetic access to 1,2‐bifunctional compounds. Furthermore, the regioselective synthesis of non‐racemic amino ethers from chiral aziridine could also be achieved under mild conditions. Finally, a possible reaction
The ringopening of N-tosylaziridines with trimethylsilylated nucleophiles, catalyzed by N,N,N',N'-tetramethylethylenediamine, led to the production of beta-functionalized sulfonamides in good to excellent yields with high regioselectivity. [reaction: see text]
