Two in two: Dioxygenation of alkenyl boronic acids has been achieved with N‐hydroxyphthalimide. The two‐step process involves etherification of an alkenyl boronic acid with N‐hydroxyphthalimide followed by a [3,3] rearrangement. The dioxygenated product can then be hydrolyzed to form either the corresponding α‐hydroxy ketone or the α‐benzoyloxy ketone.
二分之二:N-羟基邻苯二甲酰亚胺已实现了烯基硼酸的双加氧反应。分两步进行,涉及烯基硼酸与N-羟基邻苯二甲酰亚胺的醚化,然后进行[3,3]重排。然后可以将双加氧产物水解形成相应的α-羟基酮或α-苯甲酰氧基酮。
