Abstract

An efficient and rapid synthesis of furo [3, 2-b] pyridine 1 is described using a one-pot Sonogashira coupling/heteroannulation sequence. Regioselective lithiation of this synthon was performed leading to various 2-substituted furo [3, 2-b] pyridines. Some of them were used as substrates for short functional synthesis of polyheterocycles.
