Y. Hashimoto et al., HIGHLY DIASTEREOSELECTIVE ADDITION OF ORGANOMETALLIC REAGENTS TO CHIRAL IMINES DERIVED FROM 1-(2-METHOXYPHENYL)ETHYLAMINE, Synlett, (9), 1995, pp. 961
The chiral imines prepared from an artificial chiral auxiliary, 1-(2-m
ethoxyphenyl)ethylamine, and various aldehydes, reacted with organolit
hium reagents to give the corresponding chiral amines with high diaste
reoselectivity.
