Functionalization of pyridyl ketones using deprotolithiation-in situ zincation
Résumé
The metallation of aryl ketones was achieved by using LiTMP in the presence of ZnCl2 center dot TMEDA, as evidenced by subsequent interception with iodine or by a palladium-catalysed cross-coupling reaction. One of the synthesized iodo ketones has been further elaborated to reach derivatives of biological interest.
