Significance
A new stereo- and regioselective lithiation of cis-stilbenes has been developed. Under the reaction conditions Hα of the vinyl moiety is preferentially abstracted. The resulting lithiated compounds can be trapped with various electrophiles leading to a broad range of valuable compounds.
