A new methodology for obtaining α-oxo ester equivalents: Sulfanylation of α-sulfonyl carboxylic esters in a solid/liquid phase transfer catalytic system

Article abstract of DOI:10.1055/s-1997-1212

A new, convenient procedure for the synthesis of a wide range of α-methylsulfanyl-α-phenylsulfonyl carboxylic esters has been developed and their facile conversion to the corresponding α-oxo esters demonstrated.
