developed for Barbier-Grignard-typealkylationreactions of simple imines, using a one-pot condensation of various aldehydes, amines (including aliphatic and chiral version), and alkyl iodides in water or aqueousmedia. The reactions proceeded efficiently at room temperature to give the desired products in moderate to good yields. Good diastereoselectivities were obtained when using L-valine methyl
开发了一种有效的In / CuI / InCl3系统,用于在水或水性介质中一锅缩合各种醛,胺(包括脂肪族和手性版本)和烷基碘的简单亚胺的Barbier-Grignard型烷基化反应。反应在室温下有效地进行,以中等至良好的产率得到所需的产物。当使用L-缬氨酸甲酯作为底物时,获得了良好的非对映选择性。
