A photocatalyzed 1,3-boron shift of allylboronic esters is reported. The boron atom migration through the allylic carbon skeleton proceeds consecutive 1,2-boron migrations and Smiles-type rearrangement to furnish a variety of terminally functionalized alkyl boronates. Several types of migrating variations of heteronuclei radicals and dearomatization processes are also tolerated, allowing for further elaboration of highly functionalized boron-containing frameworks.
报道了烯丙基硼酸酯的光催化1,3-硼迁移。硼原子通过烯丙基碳骨架的迁移是连续的1,2-硼迁移和Smiles型重排，以提供各种末端官能化的烷基硼酸酯。还可以容忍几种类型的异核自由基迁移变化和去芳构化过程，从而进一步构建高度官能化的含硼骨架。
