of the furo[3,2‐b]pyridine core as a novel scaffold for potent and highly selective inhibitors of cdc‐like kinases (CLKs) and efficient modulators of the Hedgehog signaling pathway. Initially, a diverse target compound set was prepared by synthetic sequences based on chemoselective metal‐mediatedcouplings, including assembly of the furo[3,2‐b]pyridine scaffold by copper‐mediated oxidative cyclization
