A transition-metal-free strategy for the synthesis of carboline derivatives via sequential dual C—N bond formation in a one-pot reaction is reported. Using 2,2'-dihalogenated pyridyl biaryls and primary amines as starting materials,this method efficiently constructs a series of α-, β-, γ- and δ-carbolines under alkaline conditions. The reaction proceeds smoothly in the presence of lithium tert-butoxide (t-BuOLi) or cesium carbonate (Cs2CO3) without requiring transition metal catalysts, demonstrating good functional group tolerance. This approach enables gram-scale synthesis and has been successfully applied to the preparation of the organic material 2,6-CbPy, achieving high conversion efficiency.
