[Polyfunctional molecules and their components in the processes of aromatic nucleophilic substitution. II. Nucleophilic modification of 3',5'-bis-O-(alpha,beta,alpha',beta'-tetrafluoropyridyl-gamma)thymidine].
The interaction of 3',5'-bis-O-(alpha,beta,alpha',beta'-tetrafluoropyrid-gamma-yl)thymidine with various nucleophilic reagents was studied to evaluate the possibility of molecular design of new types of nucleic acid analogues using SNAr reactions. The reactions with morpholine and sodium azide led to the introduction of one and two nucleophilic residues into each of the polyfluorinated pyridine rings. The nucleophilic polycondensation with bifunctional reagents ethylenediamine and hexamethylenediamine depended on the nature of nucleophile and reaction conditions and resulted in the formation of supramolecules containing about five or more than 20 pyrimidine bases.
