Enantioselective protonation of samarium enolates derived from α- heterosubstituted ketones and lactone by SmI2-mediated reduction

SmI2-mediated reductive cleavage of α-heterosubstituents of α-alkyl or α-aryl ketones and lactone gave the corresponding 'thermodynamic samarium enolates'. Enantioselective protonation of the samarium enolates with C2- symmetric chiral diols afforded the corresponding ketones and lactone in moderate to high enantioselectivities.

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

Asymmetric Synthesis of Ketones by SmI2-Mediated Allylation or Benzylation of Ketenes Followed by Enantioselective Protonation

SmI2-mediated allylation or benzylation of alkylarylketenes followed by enantioselective protonation with α,α'-di-o-xylenedioxide gave the corresponding ketones in 61-91percentee.
