An efficient and powerful copper-assisted method for the effective conversion of a broad range of hydroxypyridines and sodium sulfinates into their corresponding pyridinyl tosylates was developed. Key features of this base- and ligand-free protocol include using the cheap and readily available CuBr2 as a medium and the use of sodium sulfinates as formal sulfonylation reagents. A variety of functional pyridinyl tosylates could be formed with good yields, which can easily be converted into C-C and C-N bond-containing compounds. This journal is

Heteroaromatic 2-pyridyl tosylates were successfully applied as electrophiles in palladium(0)-catalyzed Mizoroki-Heck-coupling reactions to electron-rich olefins with complete aregioselectivity. This protocol represents a general strategy for the application of pyridyl tosylates and mesylates in the Mizoroki-Heck coupling. The catalytic system also proved adaptable to changes in the heteroaromatic core as well as large-scale applications. Finally, the synthetic utility of the functionalized α-heteroarylvinyl amides was established providing straightforward access to highly functionalized heteroaromatic compounds including chiral benzylic amide derivatives.
