Abstract
A simple and efficient synthetic methodology has been developed via Krapcho decarboxylation to construct four new N2,N9-benzylated quaternary β-carbolin-3-ium bromide salts (5a-d) by treating ethyl-β-carboline-3-carboxylate (4) with various substituted benzyl bromides in the presence of NaH in DMF under refluxing conditions with very good to excellent yields (81-95%).
