with glycidyl ethers of 3-arylcoumarins were studied. A series of cytisine–coumarin conjugates were synthesized via regiospecific opening of the oxirane ring by cytisine. Methods for conjugating anabasine and cytisine with 3-arylcoumarins through a but-2-ynyl linker via reactions of propargyl ethers of 7-hydroxy- and 6-hydroxy-3-arylcoumarins with the alkaloids were proposed.
