Herein, we developed a series of compounds featuring spiro[3-arylcyclohexanone]oxindoles through Barbas [4 + 2] cycloaddition reactions between isatylidene malononitrile and α,β-unsaturated ketones using L-proline as an organocatalyst. The reported methodology offers many advantages such as mild reaction conditions, diverse substrate scope with high yields, easy reaction setup, and use of easily synthesizable
在此,我们以
L-脯氨酸为有机催化剂,通过异亚叉基
丙二腈与α,β-不饱和酮之间的Barbas [4 + 2]环加成反应,开发了一系列以螺[3-芳基
环己酮]羟
吲哚为特征的化合物。所报道的方法具有许多优点,例如温和的反应条件、高产率的多样化底物范围、简单的反应设置以及使用易于合成的起始材料。
