The analogous asymmetric synthesis starting from the (R)-enantiomer of 3-oxocyclohexanecarboxylic acid (XV) was also reported. The chiral (R)-keto acid (XV), prepared by resolution of the racemic acid (XII) with brucine, was coupled with tetrahydropyridine (V) to give keto amide (XVI). Protection as the ethylene ketal (XVII), followed by amide reduction and acidic ketal hydrolysis, furnished the (R)-amino ketone (XVIII). This was converted into the title compound by addition of phenylmagnesium bromide, followed by acidic dehydration and separation of isomers as in Scheme 19758501a.
