Enantioselective Protonation of Samarium Enolates by a C2-Symmetric Chiral Diol

High enantioselectivity (up to 97percentee) have been achieved in the protonation of samarium enolates which were generated by SmI2-mediated cross-coupling reaction between unsymmetrical dialkylketene and allyl iodide, using, using a C2-symmetr

Stereoisomerization of Ketene Imines

Barriers to racemization in solution of the ketene imines 1a - y and X-ray structures of the ketene imines 1s and z are described.Similar to allenes all ketene imines have dihedral angles of 90 deg between the C- and N-substituents.The barriers to racemization range from 30 to 63 kJmol-1 and are lowered by electron attracting substituents on C and N.The barriers of m- and p-substituted N-arylketene imines give a linear Hammett correlation with ?- constants.N-Arylketene imines racemize through inversion at nitrogen and simultaneous rotation of the aryl group around the N - aryl bond.
