Iron-Catalyzed Regio- and Stereoselective Conjugate Addition of Aryl-Grignard Reagents to α,β,γ,δ-Unsaturated Sulfones and its Synthetic Application
Autor: Naoki Hirone, Hirokazu Urabe, Takeshi Hata, Yun Taek Oh, Takuya Nakada
Publikováno v: Advanced Synthesis & Catalysis. 355(No. 9):1736-1740
The iron-catalyzed δ-addition of aryl-Grignard reagents to α,β,γ,δ-unsaturated sulfones proceeded in a regio- and stereoselective manner to give cis-4-aryl-2-alkenyl sulfones. Allylic alkylation of the resultant products was performed without is
