The reaction of 2-aryl-2,3-epoxy acylates with Lewis acids was examined in detail. Cyclic 2-aryl-2,3-epoxy acylates afforded the rearranged products via the C2-carbocation intermediates obtained by the C2-cleavage of the oxirane rings. On the other hand, acyclic 2-aryl-2,3-epoxy acylates gave the rearranged products via the phenonium ion intermediates obtained by the C3-cleavage of the oxirane rings
详细检查了2-芳基-2,3-环氧酰化物与路易斯酸的反应。环状2-芳基-2,3-环氧酰化物通过通过环氧乙烷环的C 2裂解获得的C 2羰基化中间体提供了重排产物。另一方面,无环的2-芳基-2,3-环氧酰化物通过通过环氧乙烷环的C 3裂解获得的离子中间体得到重排产物。该方法还应用于光学活性的苄基季碳中心的合成。
