(−)1(S),2(S),4(R),6(R)-1,2,3,4,5,6-Hexahydro-2,6-methano-8-methoxy- 1,3,4,6-tetramethyl-3-benzazocine has been synthesised in 86 % enandomeric excess from the α-(ν6-chromium tricarbonyl) complex of 1(S),1′(R)-1,2-dihydro-7-methoxy-1,4-dimethyl-1-(N-methyl-N-trifluoroacetamido-1′-methylethan-2′-yl)naphthalene. A precursor of this compound is 2(R),4(S)-4-(3-methoxyphenyl)-2,4-dimethylcyclohexanone which
