Abstract

Naturally occurring α-amino acid successfully catalyzed cycloaddition of aziridine with carbon dioxide to afford 5-aryl-2-oxazolisinones under mild conditions without the need of any additives. The scope of this reaction is very general, providing the corresponding products in good yields and excellent regioselectivity (87: 13–100: 0) regardless of the α- amino acid examined and a wide variety of N-substituted aziridines employed. Two ...
