4) of the chiral auxiliary, the 2-cyclohexyl-1-(pyridin-2-yl)ethylamine was obtained with good enantiomeric excess (80-96%). However, the yield of the last step was low (35-40%) C.K. Miao, R. Sorcek, and P.-J. Jones Tetrahedron Lett. 34 1993 2259

Another very attractive N-substituent is the tert-butyl sulfinyl group, however the enantiopure tert-butanesulfinamide is much more expensive than the (S)-(+)-p-toluenesulfinamide, therefore starting our investigation, we decided to use the latter.
