(S,S)-(+)-pseudoephedrine as chiral auxiliary in asymmetric aza-Michael reactions. Unexpected selectivity change when manipulating the structure of the auxiliary

The asymmetric aza-Michael reaction of metal benzylamides to α,β-unsaturated amides derived from the chiral amino alcohol (S,S)-(+)-pseudoephedrine has been studied in detail. A deep study of the most important experimental parameters (solvent, temperatur
