N-sulfinyl metalloenamine conjugate additions: Asymmetric synthesis of piperidines
Peltier, Hillary M.,Ellman, Jonathan A.
, p. 7342 - 7345 (2005)
The first examples of conjugate additions of W-tert-butanesulfmyl metalloenamines are reported. Highly stereoselective conjugate additions (97:3 to 99:1 dr) were observed between metalloenamines derived from N-sulfinyl ketimines and α,β-unsaturated ketone
