Metalated fluoropyridines and fluoroquinolines as reactive intermediates: new ways for their regioselective generation
1994
Abstract
The mixt. of lithium diisopropylamide and potassium tert-butoxide (LIDA-KOR reagent) is a powerful base which can be advantageously employed for the regioselective deprotonation of fluoropyridines and, in particular, 3-fluoroquinoline. A novel cyclization process was elaborated for the prepn. of the latter product. [on SciFinder (R)]
