Abstract An effective method for the synthesis of vinyl thioethers through the conjugate addition of ethanethiol to electron-deficient alkynes promoted by BF 3 ·Et 2 O has been developed. Electron-deficient internal alkynes react with ethanethiol in this system to yield mainly Z -isomer of vinyl thioether adducts, while electron-deficient terminal alkynes afford mainly E -isomer of vinyl thioether
The invention relates to protein conjugates that contain a protein kinase containing a cysteine residue in the ATP binding site and an inhibitor that is covalently and irreversibly bonded to said cysteine residue, such that the activity of the protein kinase is irreversibly inhibited. The invention also relates to compounds that irreversibly inhibit protein kinases.
