Pd-catalyzed halocyclizations of unactivated 1,6-diynes through a formal anti-carbopalladation/bromide radical cascade
《Chinese Chemical Letters》2021年第9期2756-2760,共5页Zhihua Wang Li Wei Zhendong Cheng Jianhui Xia Zhiyuan Chen 
National Natural Science Foundation of China(No.21961015);the Natural Science Foundation of Jiangxi Province(No.20202ACBL203005)for financial support;the Open Project Program of Polymer Engineering Research Center,Jiangxi Science&Technology Normal University(No.KFGJ18014)。
We report a Pd-catalyzed halocyclization of unactivated 1,6-diynes with N-bromosuccinimide(NBS).This approach produces stereo-defined dibromo substituted dihydropyrans,tetrahydropyridines,and 3-methylene cyclohexenes ...
