    • نبذة مختصرة :
      International audience; The regioselective functionalization of aza-ullazines has been successfully realized for the first time by either metalation using BuLi-containing aggregates (BuLi-LiDMAE) or electrophilic substitution. Mono and di-bromo-derivatives were obtained in good to excellent yields and further successfully converted into aryl and alkynyl azaullazine derivatives via Suzuki and Sonogashira cross-coupling reactions.
