A Study of Asymmetric Induction during the Addition of Enolate Nucleophiles, Having Sulfoximine Chiral Auxiliaries, to Diene-Molybdenum and Dienyliron Complexes

Pearson, Anthony J.,Blystone, Sheri L.,Nar, Herbert,Pinkerton, A. Alan,Roden, Brian A.,Yoon, Jaeyon

, p. 134 - 144 (2007/10/02)

Asymmetric induction as high as 90percent ee was obtained during the reaction of enolates, derived from optically pure sulfoximinyl esters of type 16, with the cycloheptadiene-Mo(CO)2Cp cation.Lower, but still significant asymmetric induction was observed
