Heteroaromatic tosylates as electrophiles in regioselective Mizoroki-Heck-coupling reactions with electron-rich olefins

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.

Preparation of 2-substituted pyridines

This invention relates to a process for preparing 2-substituted pyridines via metal halogen exchange with sec-butyllithium on optionally substituted 2-bromo or 2-iodopyridines. The resulting lithopyridine intermediate is reacted with an electrophile to provide the desired 2-substituted pyridine. The substitution of sec-butyllithium for n-butyllithium in such a process results in an enhanced yield and purity of the desired 2-substituted pyridine.
