The Michael addition of malonates to aromatic α,β-unsaturated aldehydes was efficiently organocatalyzed by (S)-2-[bis(3,4,5-trifluorophenyl)trimethylsilanyoxymethyl]pyrrolidine, derived from L-proline to afford the corresponding adducts in good yields with good to excellent enantioselectivities.
L-脯氨酸衍生的(S)-2-[双(3,4,5-三氟苯基)三甲基硅氧甲基]吡咯烷有效地有机催化了芳香族α,β-不饱和醛与丙二酸盐的迈克尔加成反应,以良好的产率和出色的对映选择性得到了相应的加合物。
