摘要

采用(Z)钾和(E)-丁烯三氟硼酸钾制备了一种高度非对位选择性的乙醛丁烯基化反应方案。以苯并脒肟为再生催化剂，采用简单的提取工艺回收。该方法简便、快速，对不同醛类具有区域选择性和化学选择性。无需进一步提纯，均烯丙醇的产率良好至优异。

Benzamidoxime-Mediated Crotylation of Aldehydes using Potassium (Z) and (E)-Crotyltrifluoroborates

A highly diastereoselective protocol for the crotylation reaction of aldehydes using potassium (Z) and (E)-crotytrifluoroborates was developed. Benzamidoxime was employed as a renewable catalyst, which was easily recovered through a simple extraction process. This method proved to be simple, fast, regio- and chemoselective for different aldehydes. The corresponding homoallylic alcohols were obtained in good to excellent yields without the need of further purification.
