which could serve as valuable synthetic building blocks. This is also the first time that a ketone has been used as the electrophile and acrolein as the nucleophile in a highly enantioselective catalytic asymmetric MBH reaction. Hatakeyama's catalyst, β-isocupreidine (1), turned out to be a powerful catalyst for this transformation.

靛红和
丙烯醛的高度对映选择性 Morita-Baylis-Hillman (MBH) 反应,以提供富含对映异构体的 3-取代 3-羟基
吲哚,其可作为有价值的合成构建块。这也是第一次在高度对映选择性催化不对称 MBH 反应中使用酮作为亲电试剂和
丙烯醛作为亲核试剂。Hatakeyama 的催化剂 β-异
铜吡啶 (1) 被证明是这种转变的强大催化剂。
