Abstract
- A highly efficient catalytic asymmetric formal [3+2] cycloaddition reaction of 5-alkoxyoxazoles with azodicarboxylate compounds has been realized by a chiral N,Nā²-dioxide/Co(BF<subscript>4</subscript>)<subscript>2</subscript>·6H<subscript>2</subscript>O complex. A series of poly-substituted 1,2,4-triazolines compounds were obtained in moderate to excellent yields (70ā99%) with excellent enantioselectivities (82ā98% ee). [ABSTRACT FROM AUTHOR]
