A Ni-catalyzed ring-opening of α-hydroxycyclobutenones is reported herein. A remarkable ligand effect was observed during transformations following the ring-opening. The employment of PPh₃ leads to the formation of 2-furanones 2 through a migration of an alkoxyl group, and 2-furanones 3 were generated through a migration of hydrogen in the presence of Xantphos, affording a divergent approach to 2-furanones bearing multiple functional groups.

镍催化α-羟基环丁烯酮的开环，具有显着的配体效应

本文报道了Ni催化的α-羟基环丁烯酮的开环。开环后的转化过程中观察到了显着的配体效应。PPh _3的使用通过烷氧基的迁移导致形成2-呋喃酮2，而在Xantphos的存在下通过氢的迁移生成2-呋喃酮3，从而提供了一种对带有多个苯酚的2-呋喃酮进行发散的方法。功能组。
