provides a route to access these products directly fromterminal alkynes and the parent pyridine, and without prefunctionalization of the pyridine core. In addition, (Z)-alk-2-enylpyridines can be prepared via a related procedure. These reactions are used to synthesize a number of new alkynyl- and alkenyl-substituted pyridines in one pot. pyridine - copper - catalytic - alkyne - alkene
