Abstract
Abstract A postsynthetic, on-column Sonogashira reaction was applied on DNA molecules modified by 2-or 4-iodophenylmethylglycerol in the middle of the sequence, to give the corresponding ortho-and para-twisted intercalating nucleic acids (TINA) with 1-, 2-, and 4- ethynylpyrene residues. The convenient synthesis of 2-and 4-ethynylpyrenes started from the hydrogenolysis of pyrene that has had the sulfur removed and separation of 4, 5, 9, 10 ...
