of potassium tert-butoxide undergoes a novel heteroaromatic CHinsertion of alkylidenecarbenes generated in situ to give the corresponding furopyridine derivatives. The heteroaromatic CHinsertion shows an extremely high selectivity compared with the possible aliphatic CHinsertion. This process is also applied to furoquinoline synthesis.
