| Two classic chiral amines, Enders' RAMP (1) and Rossiter's S-MAPP(2), have been used as non-transferable ligands in organocuprate conjugate additions for the addition of n-butyl and methyl to chalcone and 2-cyclohexenone. These results will be compared to their silylated analogues 3, 4. Enantiomeric excesses of 90% and nearly quantitative chemical yields were observed in some cases for the silylated analogues. |
