7-Chlorothieno[3,2-b]pyridine-2-carbaldehyde features a fused thienopyridine core with a chlorine substituent at the 7-position and an aldehyde group at the 2-position. This electron-deficient scaffold integrates readily into heterocyclic architectures, enabling efficient coupling in cross-coupling and condensation reactions under standard conditions.
7-Chlorothieno[3,2-b]pyridine-2-carbaldehyde serves as a versatile heterocyclic building block for medicinal chemistry and materials science applications. Its aldehyde functionality enables efficient coupling reactions, including reductive amination and Ugi-type condensations, while the fused thienopyridine core offers enhanced metabolic stability and π-conjugation. The chloro substituent provides a handle for further functionalization via palladium-catalyzed cross-coupling. Bench-stable and readily purified by flash chromatography, it facilitates streamlined synthesis of complex scaffolds.
