, p. 19 - 25 (2002)
A number of derivatives of 5-(2-aminoethyl)bicyclo[2.2.1]hept-2-ene (85-90% of the endo isomer) were synthesized by reactions with p-nitrobenzenesulfonyl chloride, p-toluenesulfonyl chloride, benzoyl chloride, p-nitrobenzoyl chloride, benzyl isocyanate, m-tolyl isocyanate, phenyl isothiocyanate, and endic anhydride. By reactions of the resulting sulfon- and carboxamides with peroxyphthalic acid generated in situ from phthalic anhydride and 40-45% hydrogen peroxide the corresponding epoxy derivatives were obtained. These reactions were not accompanied by heterocyclization into azabrendane derivatives, which is typical of homologous N-(p-nitrophenylsulfonyl)-endo-5-aminomethylbicyclo[2.2.1]hept-2-ene.

We have exploited the concept of multivalency in the context of DNA recognition, using novel chemistry to synthesize a new type of bis-intercalator with unusual sequence-selectivity. Bis-intercalation has been observed previously, but design principles for de novo construction of such molecules are not known. Our compounds feature two aromatic moieties projecting from a rigid, polynorbornane-based scaffold. The length and character of the backbone as well as the identity of the intercalators were varied, resulting in mono- or divalent recognition of the double helix with varying affinity. Our lead compound proved to be a moderately sequence-selective bis-intercalator with an unwinding angle of 27° and a binding constant of about 8 μM. 9-Aminoacridine rings were preferred over acridine carboxamides or naphthalimides, and a rigid [3]-polynorbornane scaffold was superior to a [5]-polynorbornane. The flexibility of the linker connecting the rings to the scaffold, although less influential, could affect the strength and character of the DNA binding.
