NucleophilicOrthoAllylation of Aryl and Heteroaryl Sulfoxides
摘要:
Aryl and heteroaryl sulf oxides undergo ortho allylation upon treatment with Tf2O and allyisilanes. The method complements the use of sulfoxides to direct ortho-metalation and reaction with electrophiles as it allows allylic carbon nucleophiles to be added ortho to the directing group in a metal-free process. The versatile sulfide adducts can be selectively manipulated using various methods Including Kumada-Corriu cross-coupling of the organosulfanyl group.
