Highly stereoselective imidazolethiones mediated Friedel–Crafts alkylation of indole derivatives

The asymmetric Friedel–Crafts alkylation of indoles with α ,β-unsaturated aldehydes was promoted by the novel imidazolethiones to afford the corresponding adducts in moderate to excellent yields and high enantioselectivities under mild reaction conditions. The asymmetric Friedel–Crafts alkylation of...
