设计、合成了3种C2对称脯氨酸衍生物催化剂,将其用于不对称Aldol反应,得到了anti构型的主产物,表现出很好的化学产率(82%~92%)和最高达90%e.e.的对映选择性及anti/syn=83/17的非对映选择性。
Three C2 symmetric proline derivatives catalysts were designed and synthesized, which were used in the asymmetric Aldol reaction to obtain the main products of anti configuration with good chemical yield (82% -92%) and highest Enantioselectivity up to 90% ee and anti / syn = 83/17 diastereoselectivity.
