title: Regiocontrolled deprotonative-zincation of bromopyridines using aminozincates.
abstract: Regiochemistry in the deprotonation of bromopyridines was found to be greatly influenced by the choice of metal amide base, and DA-zincate and TMP-zincate turned out to be excellent complementary practical agents for regioselective metalation of bromopyridines.
