Indium triflate-catalyzed ring opening of aziridines with carboxylic acids
Aziridines react smoothly with carboxylicacids in the presence of a catalytic amount of indium triflate at ambient temperature to afford the corresponding β-aminoacetates and benzoates in high yields with high regioselectivity.

The ring-opening of N-tosylaziridines with various acid anhydrides catalyzed by 5 mol % of 1,5,7-triazabicyclo[4,4,0]dec-5-ene (TBD) afforded the corresponding β-amino esters in excellent yields under mild reaction conditions. Polymer-supported catalyst, PS-TBD also acts as a good catalyst for this reaction. PS-TBD was easily recovered and reused with minimal loss of activity.
