Florian Viton, Bernardinelli,E Peter ,

The single coordination-site transition metal Lewis acids [CpM(BIPHOP-F)][SbF6] (M = Fe, Ru) catalyze the [3+2] dipolar cycloaddition reaction between reactive nitrones and alpha,beta-unsaturated aldehydes to give chiral isoxazolidines with ee values of 75 to >96%. The stereochemistry of the major enantiomer is consistent with an endo approach of the nitrone to the Calpha-Si-face of the enal in the s-trans conformation in the (R,R)-catalyst site. The absolute configuration is based on an X-ray structure determination.
