Organocatalyzed asymmetric α-alkylation of aldehydes with 3-hydroxy-3-indolylox-indoles in aqueous media has been developed. The reactions proceeded efficiently in the presence of the MacMillan catalyst to give the desired products in good to excellent yields with moderate diastereoselectivities and excellent enantioselectivities.
在水介质中开发了醛与 3-hydroxy-3-indolylox-indoles 的有机催化不对称δ-烷基化反应。在 MacMillan 催化剂的作用下,反应高效进行,以良好至极佳的产率、中等的非对映选择性和极佳的对映选择性得到了所需产物。
