Asymmetric Allylic C-H Alkylation via Palladium(II)/ cis-ArSOX Catalysis
We report the development of Pd(II)/cis-aryl sulfoxide-oxazoline (cis-ArSOX) catalysts for asymmetric C-H alkylation of terminal olefins with a variety of synthetically versatile nucleophiles. The modular, tunable, and oxidatively stable ArSOX scaffold is key to the unprecedented broad scope and high enantioselectivity (37 examples, avg. > 90% ee). Pd(II)/cis-ArSOX is unique in its ability to effect high reactivity and catalyst-controlled diastereoselectivity on the alkylation of aliphatic olefins. We anticipate that this new chiral ligand class will find use in other transition metal catalyzed processes that operate under oxidative conditions.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4923-87-9, help many people in the next few years.Quality Control of 5-Bromobenzothiophene
