has been synthesised in 86 % enantiomeric excess from the α-(η6-chromium tricarbonyl) complex of 1 (S), 1′(R)- 1,2-dihydro-7-methoxy- 1,4-dimethyl - 1 -(N-methylN-trifluoroacetamido- 1′-methylethan-2′-yl)naphthalene. A precursor of this compound is 2(R),4(S)-4-(3-methoxyphenyl)-2,4-dimethylcyclohexanone which was obtained through an Enders' type C-methylation reaction of 4-(3-methoxyphenyl)4-methylcyclohexanone
