Herein, we report that palladium catalyzes the borylative cyclization of α-(2-bromoaryl) ketones to afford 1,2-benzoxaborinines. The developed system is compatible with a variety of functionalities (Me, t-Bu, OMe, NMe2, F, Cl, CN, CF3, CO2Me, and heteroaryl groups) and is applicable to the synthesis of B–O-containing tri- and tetracyclic fused-ring compounds.
在此,我们报道了钯催化 α-(2-溴芳基) 酮的硼化环化以提供 1,2-苯并氧杂环胺。所开发的体系与多种官能团(Me、t -Bu、OMe、NMe 2、F、Cl、CN、CF 3、CO 2 Me 和杂芳基)兼容,适用于 B-O- 的合成。含有三环和四环稠环化合物。
