synthesis of α-oxygenated carbonyl compounds and catechols is the treatment of a carbonyl compound or a phenol with an electrophilic oxygen source. As an alternative approach to these important structures, formal [3,3]-rearrangements of N-enoxyphthalimides, N-enoxyisoindolinones, and N-aryloxyphthalimides have been explored. When used in combination with an initial Chan-Lam coupling, these transformations
合成α-氧化羰基化合物和邻苯二酚的常用方法是用亲电子氧源处理羰基化合物或苯酚。作为这些重要结构的替代方法,已经研究了N-烯氧基邻苯二甲酰亚胺,N-烯氧基异吲哚满酮和N-芳氧基邻苯二甲酰亚胺的形式[3,3]重排。当与初始Chan-Lam偶联结合使用时,这些转化有助于烯基硼酸的双氧合以合成α-加氧的酮和芳基硼酸的双氧合以合成儿茶酚。N-烯氧基异吲哚啉酮的重排也已显示为非对映选择性的。
