The reaction of α-lithio aryl methyl sulfoxides with a limited amount of chiral carboxylates (R2-CO-O-R*) was found to be an enantiomer-differentiating reaction, affording the corresponding optically active β-keto sulfoxides (3), tog
The preparation of optically active β-keto sulfoxides by the reaction of α-lithiomethyl p-tolyl sulfoxide with ethyl carboxylates in the presence of (-)-sparteine
