The syntheses of the N-protected forms of the cytosine homodimer 1, the guanine cytosine heterodimer 2, and the guanine homodimer 3 are described. Derivatization of these dimers, as well as the protected monomers corresponding to 4 and 5, with ω-methoxypoly(ethylene glycol)-α-carboxylic acid 26 and subsequent deprotection formed the amides 29, 31, 33, 35, and 37. The binding properties of these solubilized compounds in DMSO-d6 were examined using 1H NMR.
