The enantioselective carbolithiation of ortho-substituted (E)-β-methylstyrenes provides access to chiral lithiated intermediates with broad synthetic potential. Specifically, β-methylstyrenes with o-aminomethyl, ether, and oxazoline groups have been employed in the synthesis of chiral aromatics and heteroaromatics such as isoquinolines, isoquinolinones, benzofurans, and isobenzofuranones.
