We demonstrated the intermolecular [2+2+2] cycloaddition of aryl- and trifluoromethyl-substituted internalalkyne and ethyl cyanoformate, and succeeded in constructing the pyridine derivatives using the CoI 2 /dcype/Zn catalyst system. The reaction proceeded with a high regioselectivity, and two trifluoromethyl-substituted ethyl picolinate derivatives were obtained as a single regioisomer.
