A Novel and Chemoselective Synthesis of 2-Aryloxazolines and Bis-oxazolines Catalyzed by Bi(III) Salts

Abstract

Different arylnitriles react with β-aminoalcohols in the presence of catalytic amounts of Bi(III) salts such as Bi(TFA)3, Bi(OTf)3 and BiOClO4·xH2O producing the corresponding 2-aryl­oxazolines in high yields. Selective synthesis of mono- and bis-oxazolines from dicyanobenzenes and selective conversion of arylnitriles to their 2-oxazolines in the presence of alkylnitriles can be considered as noteworthy advantages of this method.
