The regiochemistry of the Michael addition of thiols to unsymmetrical fumaric derivatives was investigated. Conjugate addition of thiols to unsymmetrical fumaric diester was well controlled by the presence of lithium cation and one of the two possibl

Unsymmetrically substituted fumaric esters underwent highly regioselective conjugate addition of thiols in the presence of a lithium cation in non-coordinative media.

Fumaric derivatives are recognizade as useful C4 building blocks in organic synthesis. To avoid unnecesary regioisomeric problems, symmetrically substituted fumaric derivatives are usually used. It...

The regiochemistry of the Michael addition of thiols to tertiary fumaric amide esters was efficiently controlled in the presence or absence of base; either of the two isomers was prepared in a highly selective way.
