ABSTRACT A method for the synthesis of allylboronates by iron-catalyzed boration of allylic alcohols with H3BO3 as an additive is developed. The introduction of H3BO3 promotes the cleavage of C‒O bond in allylic alcohols obviously. Functional groups, such as fluoro, chloro, bromo, alkyl, and alkoxy, are tolerated well. Thus, various allylboronates are obtained in acceptable yield. GRAPHICAL ABSTRACT
摘要 开发了一种以 H3BO3 作为添加剂通过铁催化烯丙醇硼化合成烯丙硼酸酯的方法。H3BO3 的引入明显促进了烯丙醇中 C-O 键的断裂。氟、氯、溴、烷基和烷氧基等官能团耐受性良好。因此,以可接受的产率获得了各种烯丙基硼酸酯。图形概要
