Efficient Access to Arylated Aza‐ullazines by Regioselective Functionalization of their pyridine ring by H‐Li exchange and Electrophilic Substitution.

Résumé

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 crosscoupling reactions.
