Dearomatising anionic cyclisation of N-cumyl-N-p-methoxybenzyl-4-methoxy-1-naphthamide 8 diastereoselectively generates a pyrrolidinone-fused tetralone 12 which may be transformed in seven steps to the racemic form of a known non-natural member of the aryl kainoid family 4 having potent biological activity. Key steps of the synthesis are ruthenium-catalysed oxidation of the C2-p-methoxybenzyl ring
