22 - 165Synthesis of (±)-Kainic Acid by Dearomatizing Cyclization of aLithiated N-Benzyl p-Anisamide. — Key-step in the presentednine-step synthesis of racemic kainic acid (XIII) is the stereoselective anioniccyclization of lithiated N-benzyl-p-anisamide (IV) which proceeds with loss ofaromaticity forming the bicyclic enone (V). — (CLAYDEN, JONATHAN;TCHABANENKO, KIRILL; Chem.
