A nickel-catalyzed tandem Ueno-Stork cyclization is developed to enable stereoselective 1,2-dicarbofunctionalization of cyclic alkenes and efficiently build various bicyclic products. This new protocol does not involve any toxic or difficult-to-remove tin reagent and is scalable and amenable to build all-carbon quaternary centers.
发展了一种镍催化的串联 Ueno-Stork 环化反应,实现了环状烯烃的立体选择性 1,2-二羰基官能化,并高效构建了各种双环产物。该新方法不涉及任何有毒或难以去除的锡试剂,且具有可扩展性,并适用于构建全碳季碳原子。
