Reactions of aziridines and epoxides with acetic anhydride catalyzed by an organophosphine provided the corresponding esters of β-amino alcohols and 1,2-diols in high yields, respectively.
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.
