A novel Fe(II)/diaryl prolinol catalyzed asymmetric 1,3-dipolar cycloaddition of azomethine ylides with alkenes
A novel Fe(II)/diaryl prolinol catalyzed asymmetric 1,3-dipolar cycloaddition of azomethine ylides with alkenes has been developed. In the presence of FeCl2 (10 mol %) and α,α-bis(3,5- bistrifluoromethylphenyl)prolinol L1 (10 mol %), [3+2] cycl
