Ni-Catalyzed Intramolecular Reductive 1,2-Dicarbofunctionalization of Alkene: Facile Access to Podophyllum Lignans Core

Abstract

The facile access to the tetracyclic skeleton of podophyllotoxin, a medicinally important lignan natural product, was efficiently achieved via a unique intramolecular alkylarylation of the tethered alkene in a dihalide under mild conditions using reductive nickel catalysis.
